+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Version 1.0 26th Sept 1994.
+This was the first version put onto the anonymous ftp server
+medphys.ucl.ac.uk
+
+Version 1.01 30th Sept 1994.
+This corrected a number of problems with the original code, so that it now runs
+properly on the acc (Sun ANSI C) and gcc (GNU C/C++) compilers. The original
+version only compiled properly only on g++ (GNU C++) and CC (Sun C++)
+compilers.
+
+Version 1.02 14 Oct 1994
+This release corrected a number of memory allocation errors in 'yagi', 'output'
+and 'optimise'. Memory was not always freed in earlier releases. Also, a for
+loop in all 3 programs had a calls to routines which allocated memory many
+times, when it was only needed once. The output file now has # to mark comments,
+which the gnuplot (GNU plotting program) recognises.
+
+Version 1.03
+'optimise' was compleatly re-written, so that it no longer used lots of
+tempory files on disk. This makes it much faster (6-7x on a 6ele beam ).
+
+Version 1.04 First DOS based version.
+
+Version 1.05 26 Oct 1994.
+
+Optimise now takes lots of options. You dont need such a complex command to get it to work. There are sensible defaults. Some options dont work on optimise - '-g' , '-T' , -t' and '-p'.
+
+Version 1.06 28/10/94
+
+Released on to one user. Options 'T' and 't' now work. Genetic algorithm still does, although man page mention them.
+
+Version 1.07 31/10/94
+
+Added option '-w' that averages data of 3 frequencies to build wide-band antenna. A lot of integers for best/latest design were removed, puting them instead in a structure.
+
+Version 1.08 5/11/94.
+
+Genetic algorithm works now. Parameters used internally (probability of crossover etc) may not be anywhere near optimum. GA does not seem to offer any real advantage, but early days yet.
+
+Added a new program 'rantest' to check the randome number generators are working
+okay.
+
+Version 1.09
+
+Added a facility in 'output' to print 3dB bandwidths. Removed printing of parameter 'F', as this is of little use and space is needed.
+
+Changed default elements altering form only parasitic to all elements.
+
+Corrected an error in which the .gai file prints the E-plane data and H-plane data refersed.
+
+Version 1.10 Thursday 3 October 1995.
+
+Corrected a bug where 'output' would fail, due to a problem with assuming
+where the 3dB points were in the H plane. Added options '-i' so you can
+completely ignore 3dB beamwidths, also options '-E' and '-H' so you
+can specify the maximum value of theta and phi over which the beamwidths
+are calculated. A better fix, wherby the program always gets it right
+will possibly be added, but this will slow the program considerably. Needs
+some though of the best way to do this.
+
+Program now computes the maximum level of any sidelobe. Obviously
+there no point worrying about getting a good FB, if one of the other
+lobes is more significant.
+
+Version 1.11 Never released.
+
+Changed most of the things done in 1.10! The '-i' option on optimise has been droped, but insread a '-e' option was added to avoid calculation of the E-palne
+BW and a -h to avoid calculation of the H-plane BW.
+
+Version 1.12
+
+Changed GA length. eg min length can now go below 0.4 lambda. Changed
+program 'first; to calculate the according to the well known DL6WU antennnas.
+
+fitness computed in a different was. weight.swr=1-log10(swr), rather than the
+old 1-((swr-1)/(swr+1))^2.*weight.gain.
+
+'yagi' now prints the element currents, as a row of *'s, if the -d option is
+added.
+
+Version 1.13 16th Oct 2000
+Much improved documentation. There are now some html files on my web

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+Yagiusa- 1.19 10/6/2005
+Added a new program 'dipole' that finds the impedance of a
+simple dipole.
+Changed the file layout, to sepparte man pages from htlm pages.
+
+YagiUda-1.1.18, 29/10/2000
+
+Generate output for gnuplot on a linear scale in addition to a log scale
+Changed the names of a few files, to be more explicit
+Cleaned up a lot of code, so gcc generates far less warnings.
+Corrected a bug in first.c so that it works okay for non-uniform diamater elements.
+included stdlib.h if possible in all files, to remove a linux bug
+Correct a few spelling errors in first and input.
+Changed input so it can handle antennas with different diameter elements.

+TITLE: YagiUda-1.18.tar.gz
+
+PURPOSE: To analyse performance of Yagi-Uda antennas. You
+give the dimensions and positions of each element, and the
+program calculates gain, input impedance, front-to back ratio,
+beam-patterns etc. An optimisation program 'optimise' tries to
+optimise a design. The optimiser can also tell you the sensitivity
+of a good design, to small mechanical errors.

+Here is a list of things I consider need improving in the programs,
+as of version 1.08.
+
+
+1) Some graphical interface would be nice. I personally am not much
+into writing X or Windows software, but realise that it would be better
+if the program run under one or the other (both??). It would be nice to
+move and adjust elements with a mouse, and the program recalculate
+performance.
+
+2) The functions that do the LU decomposition and back substitution are
+a bit wasteful of time and storage space, since they are basically real
+routines, being pushed to do complex maths. Hence rewriting them to
+handle complex maths would be very nice.
+
+3) The optimisation routine adjusts elements randomly. Whist I feel this
+is useful, since you could otherwise reach a local optimum in
+performance, but really not have a global optimum, its rather slow. The
+option of a more intelligent optimisation algorithm (stepest decent etc)
+would be nice. The GA is one answer to this.
+
+4) Identify and remove all unknown bugs!
+
+5) Optimise parameters og the genetic algorithm (GA).
+
+If anyone intends to re-write some of the code, please e-mail me and tell
+me what you are doing. Then I will be able to keep a track of what
+people are doing. It might save duplication. If you then send me updated
+files, I'll put on an ftp site.

+# Of course, Automake must honor this variable whenever it calls a

+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top

+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+.SH NAME
+dipole \- Yagi-Uda project file. Computez Z of a dipole
+.SH SYNOPSIS
+.B yagi
+[
+.B -\ dhps
+]
+filename
+.SH DESCRIPTION
+The program
+.I dipole
+is one of a number of executable programs that forms part of a set of
+programs, collectively known as the
+.I Yagi-Uda project
+, which were designed for analysis and optimisation of Yagi-Uda antennas.
+.I dipole
+Was added to find the impedance of just a single dipole.
+.br

+
+.SH PLATFORMS
+Only UNIX versions have been produced. I can't be bothered
+with brain-dead operating systems like Windoze.
+.SH BUGS
+Bugs should be reported to
+.BR david.kirkby at onetel.net .
+Bugs tend actually to be fixed if they can be isolated, so it is in your
+interest to report them in such a way that they can be easily reproduced.
+If the input file is edited manually and done incorrectly, there can be unpredictable results.
+
+.SH AUTHORS
+
+Dr. David Kirkby G8WRB (david.kirkby at onetel.net), with
+help with converting to DOS from Dr. Joe Mack NA3T (mack at fcrfv2.ncifcrf.gov).

+<H2>DESCRIPTION</H2><PRE>
+ The program <B>first</B> is one of a number of executable programs
+ that forms part of a set of programs, collectively known as
+ the <I>Yagi</I>-<I>Uda</I> <I>project</I> , which were designed for analysis and
+ optimisation of Yagi-Uda antennas. <I>first</I> is used to define
+ an antenna quickly, if you are not interested in analysing a
+ specific design (in which case use <I>input</I> ) but need to get a
+ design that is half-way reasonable so that it may be optim-
+ ised. It is much faster in use (since its not interactive)
+ than <I>input</I> The design methodology that <I>first</I> is the DL6WU
+ antenna designs, which are valid for 10 or more elements,
+ although <I>first</I> will calculate for any number of elements.
+ DL6WU reccomends a folded dipole, but the designs here are
+ for a simple dipole, since I don't yet know how to calculate
+ the self and mutual impedances of folded dipoles.
+
+
+</PRE>
+<H2>LIMITATIONS</H2><PRE>
+ Filenames, including full path, can't exceed 90 characters.
+
+ Does not take into account the variation of impedance of a
+ dipole with change in wavelength/diameter of elements.

+
+ The DOS .EXE files as distributed require a 387 maths copro-

+<p><b><font size=+1>Designing an antenna.</font></b>
+<p><font size=+1>Several stages are needed to design a Yagi-Uda antenna
+using these tools</font>
+<p><font size=+1>1) What you do first depends on whether you have an antenna
+design you wish to analyse (like one from a book) or if you want to design
+one using the tools in the Yagi-Uda project.</font>
+<p><font size=+1>a) If you have an antenna you wish to analyse, use <i><a href="http://www.g8wrb.org/yagi/input.html">input</a></i>
+to specify it in the form suitable for the programmes in the Yagi-Uda project.</font>
+<p><b><font size=+1>OR</font></b>
+<p><font size=+1>b) Assuming you don't know exactly what you wish to analyse,
+you can let the programme <i><a href="http://www.g8wrb.org/yagi/first.html">first</a></i>
+design you an antenna. It wont be good, but it is sufficiently close to
+optimal that it can be optimised with <i><a href="http://www.g8wrb.org/yagi/optimise.html">optimise</a></i>.</font>
+<p><font size=+1>2) Calculate the currents in the antenna, using the programme
+<u><a href="http://www.g8wrb.org/yagi/yagi.html">yagi</a></u></font>
+<p><font size=+1>3) Calculate the performance of the antenna using the
+programme
+<i><a href="http://www.g8wrb.org/yagi/output.html">output</a></i>.</font>
+<p><font size=+1>4) Look at the files created by <a href="output.html">output</a>
+to see how good the antenna is. A file<i> filename.gc</i> can be read into
+gnuplot.</font>
+<p><font size=+1>5) You may only want to do 1-4 above, but you will probably
+want to optimise the antenna, using <i><a href="http://www.g8wrb.org/yagi/optimise.html">optimise</a></i></font>
+<p><font size=+1>For more informaiton</font>
+<br><font size=+1>The programmes have on-line man pages, but there are
+available in html format too. There were converted to html format

+<H2>DESCRIPTION</H2><PRE>
+ The program <B>optimise</B> is one of a number of executable pro-
+ grams that forms part of a set of programs, collectively
+ known as the <I>Yagi</I>-<I>Uda</I> <I>project</I> , which were designed for
+ analysis and optimisation of Yagi-Uda antennas. <I>optimise</I>
+ attempts to optimise the performance of a Yagi antenna for
+ one or more parameters that are considered important, such
+ as gain, F/B ratio, VSWR etc. It does this by randomly
+ changing the lengths and positions, of one or more elements,
+ then comparing the performance before and after the change.
+ Any improvements are written to a new file called
+ <I>filename</I>.<I>bes</I> where filename is the name of the antenna
+ description file created by <I>input</I> or <I>first</I>
+
+ When Yagi's are designed on paper, or using this program,
+ its possible that they will be almost impossible to build,
+ if their performance depends too critically on the dimen-
+ sions. To determine if this is the case with a design, we
+ run optimise with just the options 't' and 'T'. These
+ specify the tolerance with which you can build the antenna,
+ expressed as a standard deviation in mm. In this case,
+ instead of trying to optimise a poor design, optimise will
+ calculate the minimum gain, maximum VSWR, and minimum FB
+ ratio of a number of designs, all slightly different from
+ the input file. 99.7% of the components lie within 3 SD of
+ the mean, so if you think you can cut elements to with 1 mm
+ 99.7% of the time, specify t0.33. If you can put them in the
+ boom to within 3 mm 99.7% of the time, specify T1.
+
+ If while <I>optimise</I> is running using the methods that require
+ weights to be attached to the gain, FB, SWR etc, it becomes
+ apparent, the weights are not optimum, its possible to pause
+ the program and re-adjust the weights. If a file with the
+ name of <I>changes</I> is created, the program will pause, then
+ request new weights are entered at the keyboard.
+
+

+<H2>AVAILABILITY</H2><PRE>
+
+</PRE>
+<H2>OPTIONS</H2><PRE>
+ -<B>d</B> Print the default values of all the configureable
+ parameters to stdout. Typing this option with any
+ option that changes a parameter (see below) will
+ display the new value of the parameter, rather than the
+ default.
+
+ -<B>h</B> Print a help message.
+
+ -<B>v</B> Print verbose status information.
+
+ -<B>w</B> Instead of optimising at one fixed frequency (the
+ design frequency), this directs the program to optimise
+ at 3 separate frequencies (lowest, design and highest)
+ then to average data at all 3. This option is better
+ for wideband antenna. Note that the input impedance
+ printed is at the design frequency, *not* averaged over
+ 3 frequencies. Averaging an impedance, is likely to
+ give a very misleading impression. The impedance aver-
+ aged over 3 frequencies can be 50+i0 Ohms, even if the
+ VSWR is very poor over all 3 frequencies, as the fol-
+ lowing 3 pieces of data show.
+ Z=147 + j 300 SWR= 15.46:1
+ Z=2 + j 100 SWR= 125:1
+ Z=1 - j 400 SWR= 3250:1
+ note in the above three cases, the average impedance is
+ 50 + j 0, but average SWR is 1130:1.
+
+ -<B>O</B> Over-optimisation allowed. By default, the program
+ does not over-optimise a parameter. For example, an SWR
+ of 1.01 is usually considered good enough and any
+ change, as long as the SWR stayed good, typically below
+ 1.1:1, would be allowed, even if the SWR rose. By
+ default, FB's of 27 dB, VSWR's of 1.1 are acceptable.
+ However, by using the -<B>O</B> option, you can insist the
+ program always improves things, no matter how good they
+ are.
+
+ centage by setting <I>boom</I>_<I>extension</I> to whatever you wish.
+ -<I>b30</I> will limit the boom to no more than 30% more than
+ the original length.
+
+ -<B>c</B><I>cleanliness</I>_<I>of</I>_<I>pattern</I>
+ Specify the number of dB down on the peak gain to aim
+ to get the pattern. Any antenna pattern cleaner than
+ this will not effect the fitness, nor will it be con-
+ sidered any better when comparing to antenna designs.
+ 20 dB seems reasonable, so the default is 20, but this
+ may of course change if it's deceided too. Check the
+ source code to be certain (see REASONABLE_SIDELOBE in
+ yagi.h).
+
+ -<B>e</B><I>elements</I>
+ is an integer which specifies the type of elements that
+ are changed in the optimisation cycle. Possible values
+ are:
+ 1 - alter only the driven element(s) length (useful to
+ bring to resonance)
+ 2 - alter only the driven element position. Don't
+ change its length.
+ 4 - alter only the reflector length. The position is
+ always at x=0.
+ 8 - alter only the director lengths. Don't change
+ positions.
+ 16 - alter only the director positions. Don't change
+ lengths.
+ 32 - randomly adjust one element length, then makes
+ all other the same. Don't change the positions.
+ 64 - apply a linear taper to the lengths.
+ 128 - Set the driven element to a resonate length. It
+ may/may-not be altered after the first run, depending
+ on the whether or not '1' is invoked too. Eg -e128
+ will make it resonate and keep it there forever. How-
+ ever '-e129' will bring to resonance, then alter to
+ maximuse performance.
+ The elements altered is made from a logical AND of the
+ above, so for example to alter everything, except the
+ driven element length, use -e30, since 2+4+8+16=30. The
+ default is equivalent to -<I>e31</I> , which changes everything
+ possible. Note the reflector position is *never*
+ changed. It's always at x=0.
+
+ greater than <I>FBratio</I> dB to be equal to <I>FBratio</I> dB. This
+ avoids optimising to a very high FB ratio, which is
+ impracticable, as the bandwidth over which this FB
+ ratio will be maintained is very small and mechanical
+ considerations will prevent you from constructing it
+ with such a high FB ratio anyway. If this was not
+ prevented, you might just happen to get an antenna with
+ 100 dB FB ratio, but poor gain and swr. Since by
+ default all parameters must improve, the optimisation
+ routine will most likely never being able to improve on
+ the 100 dB FB ratio, so no improvement will result.
+ Most people would prefer to get a few extra dB of gain,
+ even if the FB ratio dropped to 30 dB.
+
+ -<B>g</B><I>GA</I>_<I>optimisation</I>_<I>method</I>
+ Use a genetic algorithm. With the genetic algorithm,
+ the program does not take any account any of the ini-
+ tial lengths/positions of elements specified in the
+ input file. Rather it works by initialising a number of
+ different antenna, then computing a 'fitness' value for
+ each. The fitness value can depend on the gain, FB,
+ real part of the input impedance, reactive part of the
+ input impedance, VSWR or the level of the sidelobes.
+ The integer after the g tells the optimiser what to
+ consider. -g1 Use gain
+ -g2 Use FB
+ -g4 Use R
+ -g8 Use X
+ -g16 Use the SWR
+ -g32 Use the level of the sidelobes.
+
+ You can use a logical AND of these, so for example -g49
+ will use a genetic algorithm, optimising for gain, swr
+ and sidelobe level, since 1(gain)+16(SWR)+32(sidelobe
+ level)=49.
+
+ -<B>l</B><I>percent</I>
+ is a parameter (floating point number) which specifies
+ the maximum percentage change in the positions or
+ lengths of an elements at each iteration. If the option
+ is not used, it will be set internally at 10% for the
+ first 25% of the iterations, 1% for the next 25%, 0.1%
+ for the third 25% of the iterations and 0.01% for the
+ last 25% of the iterations. If set to a positive number
+ x (eg optimise -l 0.3 145e10) then the percentage will
+ be set at x% for 25% of iterations, x/10 for the next
+ 25%, x/100 for the next 25 and x/1000 for the last 25%.
+ If set to a negative number y (eg optimise -l -0.5
+ 145e10) then the paramters will stay fixed at y% (in
+ this example 0.5%) all the time.
+
+ -<B>m</B><I>min</I>_<I>offset</I>-<I>from</I>_<I>peak</I>
+ Sets the minimum angle in degrees offset from theta=90
+ degrees, where the side lobes start and the main lobe
+ finishes. The higher the gain, the smaller it should
+ be. It is set internally if not set on the command
+ line.
+
+ -<B>o</B><I>optimisation</I>_<I>criteria</I>
+ 1 - Assume better if the gain has increased.
+ 2 - Assume better if the front to back ratio has
+ improved.
+ 4 - Assume better if the real part of the input
+ impedance is closer to the value that the program was
+ compiled for, or set using the '-Z' option. This will
+ usually be 50 Ohms, but you may wish to set this to
+ 12.5 Ohms if you use a 4:1 balun. Generally you can
+ get higher gain from a Yagi if you allow the input
+ impedance to fall, but of course feeding it becomes
+ more difficult.
+ 8 - Assume better if the magnitude of the reactive
+ component of the input impedance is lower (ie. the
+ antenna is nearer resonance).
+ 16 - Assume better if the VSWR is lower.
+ 32 - Assume better if the level of all sidelobes is
+ lower.
+ The <I>optimisation</I>_<I>criteria</I> may be formed from a logical
+ AND of these numbers, so for example choosing -<I>o19</I> will
+ only consider a revised antenna better than the previ-
+ ous, if the SWR, gain and F/B ratio have all simultane-
+ ously improved.
+
+ Clearly an antenna which originally had 12 dB gain and
+ 1.01:1 VSWR but then changes to 20 dB gain @ 1.02:1
+ VSWR, would to most people be better, even though the
+ VSWR has increased. By default, <I>optimise</I> only optimises
+ to sensible maximums, so to not let the optimisation
+ stall prematurely. By running <I>optimise</I> with no argu-
+ ments, the program will list the limits of acceptabil-
+ ity. These might be typically F/B ratio > 27 dB, VSWR <
+ 1.1:1, magnitude of input reactance less than 5 Ohms and
+ the real part of the input impedance within 5 Ohms of
+ Zo. Choosing -<I>o19</I> (1+2+16=19) will optimise for gain
+ (since G=1), FB (since FB=2) and SWR (Since SWR=16), but
+ would consider a higher gain and FB ratio antenna better
+ than a previous one, even if the SWR rose, as long as it
+ stayed below 1.1:1 (or as was set during compilation).
+ The default behaviour (no options) is equivalent to -<I>o37</I>
+ which optimiseas for <B>gain(1)</B>, the real part of the input
+ <B>impedance(4)</B> and <B>sidelobes(32)</B> but this may be changed
+ at any time, so type <I>optimise</I> -<I>d</I> to check the current
+ settings. If you insist on the program optimisang for
+ the very best of all selected parameters, use the -O
+ option too, but be warned the optimisation will probely
+ stick once it gets one parameter really good.
+
+ -<B>p</B><I>population</I>
+ This determines the initial population used with the
+ genetic algorithm.
+
+ -<B>r</B><I>resistance</I>
+ When optimising an antenna, consider any input resis-
+ tance closer to Zo (usually 50 Ohms) than <I>resistance</I>
+ Ohms to be acceptable. This avoids optimising to an
+ input resistance too close to Zo, which is impractica-
+ ble, as the bandwidth over which the input resistance
+ could be maintained is very small and mechanical con-
+ siderations will prevent you from constructing the
+ antenna with such an ideal input resistance. If this
+ was not prevented, you might just happen to get an
+ antenna with an input resistance of 50.000001 Ohms, but
+ poor gain, FB and possibly even a poor swr, if the
+ antenna is well away from resonance. Since by default
+ all parameters must improve, the optimisation routine
+ will get most likely never being able to improve on the
+ antenna, whereas we might be happier with a few more dB
+ gain, if the input resistance went to 50.1 Ohms. It
+ should be noted that the default optimisation routine
+ never uses the input resistance directly (only VSWR),
+ so this option cant be used without the '-o' option to
+ optimise for other than the default parameters (gain,
+ VSWR and FB ratio).
+
+ -<B>s</B><I>swr</I>
+ When optimising an antenna, consider any SWR less than
+ <I>swr</I> to be equal to <I>swr</I> This avoids optimising to a very
+ low swr, which is impracticable, as the bandwidth over
+ which such a low swr could be maintained would be very
+ small and mechanical considerations will prevent you
+ from constructing such an antenna anyway. If this is
+ was not prevented, you might just happen to get an
+ antenna with an swr of 1.000000000001:1, but poor gain,
+ FB ratio. Since by default all parameters must improve,
+ the optimisation routine will most likely never being
+ able to improve on the antenna, even though in practice
+ you would like to get a few extra dB of gain if the SWR
+ would rise to 1.02:1. The default was equivalent to -
+ <I>s1</I>.<I>1</I> but run <I>optimise</I> -<I>d</I> to display this and any other
+ defaults.
+
+ -<B>t</B><I>length</I>_<I>tolerance</I>
+ <I>length</I>_<I>tolerance</I> is the standard deviation in mm of the
+ accuracy with which you can cut elements. Since 99.7%
+ of elements will be with 3 standard deviations of the
+ mean length (stats theory says this), set -t0.2 if vir-
+ tually all (well 99.7%) of elements are within
+ 3x0.2=0.6 mm of the correct length. This option *must*
+ be used with the '-T' option and can't be used with
+ any other options apart from
+
+ -<B>x</B><I>reactance</I>
+ When optimising an antenna, consider any input reac-
+ tance of less than <I>reactance</I> to be <I>reactance</I>. This
+ avoids over optimising the reactance, at the expense of
+ something else.
+
+ -<B>A</B><I>auto</I>_<I>gain</I>
+ When the <I>auto</I>_<I>gain</I> option is used. the program maximes
+ the gain of the antenna (ignoring all other parameters
+ such as SWR, FB ratio etc) by adjusting the length (not
+ position) of one element only. -A-1 will maximuse the
+ gain, by adjusting the length of the reflector, -A0
+ will maximise the gain by adjusting the length of the
+ driven element. Its generally *not* a good idea to max-
+ imise the gain by adjusting the driven element, but the
+ program lets you do it, but using the option -A0. Using
+ -A1 will maximise gain by adjusting the length of the
+ first director, -A2 the second director and so on, up
+ to the last director. You must check carefully that the
+ input impedance in particular does not fall to silly
+ values if you use this option. On a yagi with many ele-
+ ments (> 10 or so), you can pretty safely maximise the
+ 8th or more director, but doing it on the reflector,
+ driven element or early directors often leads to silly
+ input impedances - so beware! Note, no matter how many
+ iterations you specify, this process is only done
+ once.Its unlikely you will be able to do it again,
+ without things going out of hand, but if you must do
+ it, you must re-run 'optimise' again.
+
+ -<B>C</B><I>currents</I>_<I>similar</I>
+ If this option is used, where <I>currents</I>_<I>similar</I> is an
+ integer, the program looks to make the currents in the
+ last <I>currents</I>_<I>similar</I> elements as similar as possible.
+ It computes the sum of the squares of the deviations of
+ the absolute values of the element currents from the
+ mean. If this falls, and the criteria specified with
+ the -W option is also satisfied, the antenna is con-
+ sidered better. If <I>currents</I>_<I>similar</I> is three less than
+ the number of directors, it tries to make the currents
+ in the the directors (but ignoringing the first 3) all
+ similar. If <I>currents</I>_<I>similar</I> is equal to the number of
+ directors, it tries to make all the directors have
+ similar currents. If <I>currents</I>_<I>similar</I> is one more than
+ the number of directors, it tries to make all the
+ directors and the reflector have similar currents. If
+ <I>currents</I>_<I>similar</I> is equal to the total number of ele-
+ ments, then it fails with an error message.
+
+ -<B>F</B><I>weight</I>_<I>FB</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to the FB ratio of the antenna
+ when using the '-W' option, which calculates a fitness
+ for the antenna based on one or more parameters (FB,
+ gain, input resistance, input reactance, SWR, cleanli-
+ ness of antenna pattern). The '-F' option is similar to
+ the options -G, -P, -R, -S, -X (which specify weights
+ for gain, pattern cleanliness, input resistance, SWR
+ and input reactance). When using the -W option the
+ exact algorithm used to compute the fitness (and hence
+ the effect of this parameter) is best checked by look-
+ ing at the source code (see perform.c). This is one
+ area of constant program
+ improvement/changes/development, so its difficult to
+ say exactly the effect the parameter has. However,
+ increasing the weight of a parameter (using the -F, -G,
+ -R, -S or -X options) will make the associated parame-
+ ter have a greater effect on the fitness. However,
+ unless you optimise for a high FB ratio with the -W
+ option, then setting the -F option will have no effect.
+ For example, setting the options -F2.5 -W1 is a com-
+ plete waste of time. There you have used the -W1 option
+ to optimise only for gain (see -W option section of man
+ page) but have changed the weight of the FB ratio from
+ its default 1.0 to 2.5. If you are not optimising for
+ FB ratio, the weight you attach to it is irrelavent.
+
+ -<B>G</B><I>weight</I>_<I>gain</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to the gain of the antenna when
+ using the '-W' option, which calculates a fitness for
+ the antenna based on one or more parameters (FB, gain,
+ input resistance, input reactance, SWR, cleanliness of
+ antenna pattern). The '-G' option is similar to the
+ options -F, -P, -R, -S, -X (which specify weights for
+ FB ratio, pattern cleanliness, input resistance, SWR
+ and input reactance). When using the -W option the
+ exact algorithm used to compute the fitness (and hence

+ ter have a greater effect on the fitness. However,
+ unless you optimise for gain with the -W option, then
+ setting the -G option will have no effect. For example,
+ setting the options -G2.5 -W2 is a complete waste of
+ time. There you have used the -W2 option to optimise
+ only for FB ratio (see -W option section of man page)
+ but have changed the weight of the gain from its
+ default 1.0 to 2.5. If you are not optimising for gain,
+ the weight you attach to it is irrelavent.
+
+ -<B>K</B><I>keep</I>_<I>for</I>_<I>tries</I>
+ <I>keep</I>_<I>for</I>_<I>tries</I> is the number of tries for the optimise
+ to persist using the original data file as the starting
+ point for optimisation. By default it is 1, which means
+ the program immediately looks from a new position once
+ a better one is found. It is theeoretically possible
+ that this might result in a quick, but poor local max-
+ imum. If however, <I>keep</I>_<I>for</I>_<I>tries</I> is 1000, it will stay
+ at a position for 1000 iterations after finding the
+ last best result, before considering this to be a glo-
+ bal optimum. Then it starts for the new position. In
+ practice, I have found this option to make matters
+ worst in most cases. It was added to avoid the local-
+ minimum problem, but it appears the optimisation sur-
+ face is pretty smooth, so it just slows the program,
+ without gaining much. Anyway, it can stay as an option,
+ but check the results with/without carefully before
+ using extensively.
+
+ -<B>P</B><I>pattern</I>_<I>cleanlyiness</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to the cleanness of the antenna
+ pattern when using the '-W' option, which calculates a
+ fitness for the antenna based on one or more parameters
+ (FB, gain, input resistance, input reactance, SWR,
+ cleanliness of antenna pattern). The '-P' option is
+ similar to the options -F, -G, -R, -S, -X (which
+ specify weights for FB ratio, gain, input resistance,
+ SWR and input reactance). When using the -W option the
+ exact algorithm used to compute the fitness (and hence
+ the effect of this parameter) is best checked by look-
+ ing at the source code (see perform.c). This is one
+ area of constant program
+ improvement/changes/development, so its difficult to
+ say exactly the effect the parameter has. However,
+ increasing the weight of a parameter (using the -F, -G,
+ -R, -S or -X options) will make the associated parame-
+ ter have a greater effect on the fitness. However,
+ unless you optimise for a clean antenna pattern with
+ the -W option, then setting the -P option will have no
+ effect. For example, setting the options -P2.5 -W1 is a
+ complete waste of time. There you have used the -W1
+ option to optimise only for gain (see -W option section
+ of man page) but have changed the weight of the pattern
+ cleanliness from its default 1.0 to 2.5. If you are not
+ optimising for a clean radiation pattern, the weight
+ you attach to it is irrelavent. With appropiate use of
+ the -W option (eg -W49 for gain, SWR and a clean pat-
+ tern), the computer program finds the level of the most
+ significant sidelobe, wherever it may be outside the
+ main bean. It then optimises to reduce this. The -P
+ option tells it how much weight to put on reducing this
+ sidelobe.
+
+ -<B>R</B><I>weight</I>_<I>resistance</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to the obtaining an input resis-
+ tance close to Zo on the antenna when using the '-W'
+ option, which calculates a fitness for the antenna
+ based on one or more parameters (FB, gain, input resis-
+ tance, input reactance, SWR, cleanliness of antenna
+ pattern). The '-R' option is similar to the options -F,
+ -G, -P, -S, -X (which specify weights for FB, gain,
+ pattern cleanliness, SWR and input reactance). When
+ using the -W option the exact algorithm used to compute
+ the fitness (and hence the effect of this parameter) is
+ best checked by looking at the source code (see
+ perform.c). This is one area of constant program
+ improvement/changes/development, so its difficult to
+ say exactly the effect the parameter has. However,
+ increasing the weight of a parameter (using the -F, -G,
+ -R, -S or -X options) will make the associated parame-
+ ter have a greater effect on the fitness. However,
+ unless you optimise for an an input resistance close to
+ Zo, with the -W option, then setting the -R option will
+ have no effect. For example, setting the options -R2.5
+ -W1 is a complete waste of time. There you have used
+ the -W1 option to optimise only for gain (see -W option
+ section of man page) but have changed the weight of the
+ resistance from its default 1.0 to 2.5. If you are not
+ optimising for an input resistance close to Zo, the
+ weight you attach to it is irrelavent.
+
+ -<B>S</B><I>weight</I>_<I>swr</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to the SWR of the antenna when
+ using the '-W' option, which calculates a fitness for
+ the antenna based on one or more parameters (FB, gain,
+ input resistance, input reactance, SWR, cleanliness of
+ antenna pattern). The '-S' option is similar to the
+ options -F, -G, -P, -R, -X (which specify weights for
+ FB, gain, pattern cleanliness, input resistance and
+ input reactance). When using the -W option the exact
+ algorithm used to compute the fitness (and hence the
+ effect of this parameter) is best checked by looking at
+ the source code (see perform.c). This is one area of

+ its difficult to say exactly the effect the parameter
+ has. However, increasing the weight of a parameter
+ (using the -F, -G, -R, -S or -X options) will make the
+ associated parameter have a greater effect on the fit-
+ ness. However, unless you optimise for SWR with the -W
+ option, then setting the -S option will have no effect.
+ For example, setting the options -S2.5 -W1 is a com-
+ plete waste of time. There you have used the -W1 option
+ to optimise only for gain (see -W option section of man
+ page) but have changed the weight of the SWR from its

+ the weight you attach to it is irrelavent.
+
+ -<B>T</B><I>position</I>_<I>tolerance</I>
+ <I>position</I>_<I>tolerance</I> is the standard deviation in mm of
+ the accuracy with which you can cut elements. Since
+ 99.7% of elements will be with 3 standard deviations of
+ the correct position (stats theory says this), set -T2
+ if virtually all (well 99.7%) of elements are within

+ W1 Gain.
+ W2 FB
+ W4 R
+ W8 X
+ W16 SWR
+ W32 SIDE_LOBE
+ You can logically AND these together, so for example
+ -W3 will optimise using a weighted combination of gain
+ and FB. -W49, will use a weighted combination of gain,
+ swr and sidelobe leve, since 32+16+1=49.
+
+ -<B>X</B><I>weight</I>_<I>reactance</I>
+ is the floating point number (default 1.0) specifying
+ the weight to attach to achieving a low input reactance
+ on the antenna when using the '-W' option, which calcu-
+ lates a fitness for the antenna based on one or more
+ parameters (FB, gain, input resistance, input reac-
+ tance, SWR, cleanliness of antenna pattern). The '-X'
+ option is similar to the options -F, G, -P, -R and -S
+ (which specify weights for FB ratio, gain, pattern
+ cleanliness, input resistance, and SWR). When using the
+ -W option the exact algorithm used to compute the fit-
+ ness (and hence the effect of this parameter) is best
+ checked by looking at the source code (see perform.c).

+ ter have a greater effect on the fitness. However,

+ complete waste of time. There you have used the -W1
+ option to optimise only for gain (see -W option section
+ of man page) but have changed the weight of the reacti-
+ ance from its default 1.0 to 2.5. If you are not
+ optimising for a low input reactance, the weight you
+ attach to it is irrelavent.
+
+ -<B>Z</B><I>Zo</I>
+ <I>Zo</I> is the characteristic impedance used when evaluating
+ the VSWR, reflection coefficient and other similar cal-
+ culations. The optimiser usually tries to bring the
+ input impedance of the antenna to this value. It is set
+ by default to 50 Ohms, so the default is equivalent to
+ -<I>Z50</I> but may be set to any positive number. Set to 12.5
+ Ohms if you are going to feed the antenna with a 4:1
+ balun. Generally speaking, the gain of a Yagi can be
+ higher for low input impedances, but of course such
+ antennas are more difficult to feed.
+
+ <I>filename</I>
+ This is the name of the file containing the antenna
+ description. It is expected to be in a format created
+ by either <I>input</I> or <I>first</I> - two other programs in the
+ <I>Yagi</I>-<I>Uda</I> <I>project</I>. This is an ASCII text file.
+
+ <I>iterations</I>
+ is an integer specifying the number of iterations for
+ the optimiser to perform to try to get the best
+ antenna. Time will limit the number you choose. 1000
+ iterations of a 1ele yagi takes about 5 seconds, a 6ele
+ approximately 60 seconds, an 11 element 350 seconds, a
+ 20 element 1030 seconds, a 33ele 2440 seconds, a 50ele-
+ ment 5400 seconds, 100ele 21320 seconds all on an old
+ 25MHz 486 PC with no external cache. When using the -<I>A</I>
+ option the <I>iterations</I> is automatically set internally
+ so only one attempt is made. When using the '-t' and
+ '-T' options, <I>iterations</I> specifies the number of itera-
+ tions to attempt to get a poorer design, to check the
+ sensitivity of the design to small manufacturing toler-
+ ances.
+
+
+</PRE>
+<H2>EXAMPLES</H2><PRE>
+ Here are a number of examples of using <I>optimise</I>.
+
+ 1) optimise 5ele 1000
+
+ Here the file 5ele will be optimised using the default sys-
+ tem for 1000 iterations. The default might typically require
+ gain, FB and SWR to all improve, but this may be changed at
+ any time. In any case, the program tells you what its
+ optimising for. By default the program will only optimise to
+ the selected parameters are good, not over-optimising any
+ one at the detrement of the others.
+
+ 2) optimise -b30 -f50 -s2 5ele 1000
+
+ This is similar to above, but the boom can not extend by
+ more than 30% from its original length, FB ratios above 50
+ dB are considered acceptable, as are SWR's less than 2:1.
+ The optimised resultant antenna is likely to have better FB
+ ratio, but poorer SWR than in (1) above.
+
+ 3) optimise -o1 5ele 1000
+
+ This will simply optimise 5ele for maximum forward gain. The
+ resultant antenna may have a poor FB ratio and is likely to
+ have an unacceptably low input impedance and hence high
+ VSWR. This is not a very sensible method of optimisation.
+
+ 4) optimise -W49 -l7 5ele 10000
+
+ This will optimise the file 5ele using for 10000 iterations.
+ It will require that the weighted performance of the antenna
+ in three important parameters (gain, sidelobe level and SWR)
+ improves from one design to the next. One or two parameters
+ can actually get worst from one design to the next, but the
+ weighted performance is better. The positions of the ele-
+ ments or lengths of elements will not change by more than 7%
+ in each iteration.
+
+ 5) optimise -g -S30 -G50 -F20 -p1500 5ele 10000
+
+ This will optimise the file 5ele using a genetic algorithm.
+ 1500 antennas will be randomly designed. The performance of
+ each of these will measured using a 'fitness' function,
+ weighted 30% to SWR, 50% to gain and 20% to FB ratio. The
+ probability of breading from a pair of antennas is propor-
+ tional to the fitness function.
+
+ 6) optimise -w atv_antenna 10000
+
+ This will optimise the file atv_antenna for a best average
+ performance over a wide band. The progrram calculates the
+ gain, FB and SWR at three frequencies, then computes an
+ average (mean) performance of the antenna over the band. N
+ iterations will take 3x as long to execute as N iterations
+ on the same antenna without the '-w' option.
+
+ 7) optimise -t0.1 -T1 good_design 100
+
+ This will take the file good_design and make 100 different
+ antennas from it, to simulate the effects of building toler-
+ ances. Each element is assumed to be cut so that the mean
+ error of all elements is 0 mm, but a standard deviation of
+ 0.1 mm, so 68.4% of element lengths are within 0.1 mm, 95.4%
+ within 0.2 mm and 99.7% with in 0.3 mm. The accuracy of

+ <I>Optimise</I> will stop after the number of iterations specified
+ in the parameter <I>iterations</I>. It will also stop if a file
+ <I>stop</I> exits in the current directory of the executable
+ <I>optimise</I> This file can of course only be created using a
+ multi-tasking operating system such as Unix. It is *not*
+ advisable to stop the program by hitting the DEL key (Unix)
+ or CONTROL-C (DOS), as one of the files may be open at the
+ time, resulting in an empty file. Files are not open for any
+ longer than necessary (they are closed immediately after
+ writing to them), so this is not a likely occurrence, but
+ can still occur.

+ Both DOS and Unix versions have been built. The DOS version
+ as distributed requires a 386 PC with a 387 maths coproces-
+ sor.
+
+ Although I have altered the source to make it more compati-
+ ble with DOS (reduced file name lengths etc), my wish is to
+ build a decent program, rather than fit the program to an
+ outdated operating system. If there is a *good* reason to
+ use code that is incompatible with DOS, this will be done.
+ Since <I>optimise</I> takes a while to optimise an antenna (I've
+ optimised one design for a week), it is obviously more sen-
+ sible to build this program under a multi-tasking operating
+ system, as otherwise a PC can be tied up for days.

+<H2>BUGS</H2><PRE>
+ Bugs should be reported to <B>david.kirkby at onetel.net</B>. Bugs
+ tend actually to be fixed if they can be isolated, so it is
+ in your interest to report them in such a way that they can
+ be easily reproduced.
+
+ The program will dump core (crash) if asked to optimise a
+ 1ele beam, without any arguments. This is because a 1ele
+ beam has no parasitic elements and by default the program
+ only changes parasitic elements.
+
+ Some of the options are not checked for sensible values,
+ although most are now checked and report if they are out of
+ range.
+
+ If the user specifies very large manufacturing errors using
+ the '-t' and '-T' options, its possible for elements to
+ overlap or for element lengths to become negative. This will
+ cause numerical errors. Any reasonable values will not cause
+ this.
+
+
+ On long Yagi's (50 elements) optimise can go a bit silly. It
+ can optimise say a 1296MHz Yagi to get 20 dB at 1296 MHz,
+ but less than 0 dB at only 1 MHz away. Needs some thought!
+
+ The level of the sidelobes is not computed with the GA or
+ some other optimisation types. This will be corrected later.
+
+ All those I don't know about.

+ output - Yagi-Uda project antenna display program
+
+
+</PRE>
+<H2>SYNOPSIS</H2><PRE>
+ <B>output</B> [ <B>-</B> <B>cehps</B> ] [ -<B>E</B><I>E</I>_<I>max</I> ] [ -<B>H</B><I>Hmax</I> ] [ -<B>r</B><I>minimum</I> ] [
+ -<B>R</B><I>maximum</I> ] [ -<B>Z</B><I>Zo</I> ]
+
+ filename
+
+
+</PRE>
+<H2>DESCRIPTION</H2><PRE>
+ The program <I>output</I> is one of a number of executable programs
+ that forms part of a set of programs, collectively known as
+ the <I>Yagi</I>-<I>Uda</I> <I>project</I> , which were designed for analysis and
+ optimisation of Yagi-Uda antennas. <I>output</I> calculates the
+ gain, FB ratio, input impedance etc etc of an antenna that
+ was described by the program <I>input</I> or <I>first</I> and has had the
+ element currents calculated with the program <I>yagi</I> The data
+ about the forward gain, VSWR, FB ratio, input impedance etc
+ is written to a file <I>filename</I>.<I>dat</I> Angular data, giving the
+ variation of gain with theta and phi is put into a file
+ <I>filename</I>.<I>gai</I>
+ Sometimes the program fails to find the 3dB bandwidths in
+ the E and H planes, and bombs out with a 'zbrent' error.
+ This can occur if:
+ (1) The antenna has an almost isotropic pattern, in which
+ case its never 3dB down, so the 3dB point is undefined.
+ (2) The 3dB point is outside the assumed angular range. You
+ then have to either:
+ (a) Calculate with the -e option, which avoids calculation
+ of the 3dB E-plane beamwidth or
+ (b) Do (a) above, then find approximately where the 3dB
+ point is (from the .gai file -see later), then set options
+ -E and -H so the program calculates them properly.
+
+ The DOS .EXE files as distributed require a 387 maths copro-
+ cessor to be present and will not run without it. A 486,
+ Pentium, and I assume later processors of this series will
+ run it without any extra hardware. The DOS files are no
+ longer being maintained, so are out of sync with the latest
+ source.
+
+
+</PRE>
+<H2>OPTIONS</H2><PRE>
+ -<B>c</B> Calculate the maximum level of any sidelobe - not just
+ the rear on as the FB ratio tells us. If the sidelobe
+ and FB ratio are equal, it means the biggest sidelobe
+ is the rear one. If the Sidelobe is less than the FB
+ ratio, then another lobe is more significant. Look in
+ the '.gai' file (see below) to see where it is. This
+ option slows the program quite a bit.
+
+ -<B>e</B> Suppress calculation of the 3dB E-plane bandwidth. This
+ is sometimes necessary if the programme is unable to
+ find the 3 dB beamwidth, to prevent an error occuring.
+
+ -<B>h</B> Suppress calculation of the 3dB H-plane bandwidth. This
+ is sometimes necessary if the programme is unable to
+ find the 3 dB beamwidth, to prevent an error occuring.
+
+ -<B>p</B> Put data into a file filename.freq for reading into
+ gnuplot, and a commmand file filename.gc for gnuplot to
+ use. (run 'output -p filename' then 'gnuplot
+ filename.gc' )
+
+ -<B>s</B> Suppress all diagnostic output. By default, the program
+ print the percentage of the job completed.
+
+ -<B>E</B><I>E</I>_<I>max</I>
+ When the program computes the E-plane 3dB beamwidth, it
+ assumes the antenna pattern is 3dB down somewhere in
+ the range 90 to Emax, where E_max is by default 179
+ degrees. This can fail if it is never 3dB down in the
+ range, or if it happened to go 3dB down in two or more
+ points. You can change E_max, if you need to, but
+ rarely if every should need to. I've never seen a
+ failure here, but are guarding against one. If you dont
+ want the pattern, use the -e option instead, which
+ skips it. See also '-H' below.
+
+ -<B>H</B><I>H</I>_<I>max</I>
+ When the program computes the H-plane 3dB beamwidth, it
+ assumes the antenna pattern is 3dB down somewhere in
+ the range 0 to Hmax, where H_max is by defualt 60
+ degrees. This can fail if it is never 3dB down in the
+ range, or if it happended to go 3dB down in two or more
+ points. Also, if it goes more than 3dB down, but that
+ starts to come up again. You can change H_max, if you
+ need to, as failures do occasionally occur. If you dont
+ want the pattern use -h option instead, which will skip
+ it.
+ An obvious example of an antenna where you cant find
+ the 3dB bandwidth for the H-plane is the 1ele dipole.
+ The radiation is symmetrical about its axis, so the
+ level is the same everywhere in the H plane. The pro-
+ gram automatically avoids calculating it for a 1 ele
+ beam.
+
+
+ -<B>Z</B><I>Zo</I> Zo is the characteristic impedance used when calculat-
+ ing the VSWR. By default it's 50 Ohms, but can be
+ changed to any real, positive value.
+
+
+ <I>filename</I>
+ is the name of the file containing the antenna
+ description. It is expected to be in a format created
+ by <I>input</I> or <I>first</I> - two other programs in the <I>Yagi</I>-<I>Uda</I>
+ <I>project</I>. The is also expected to exist a binary file
+ <I>filename</I>.<I>out</I> created by typing <I>yagi</I> <I>filename</I>

+.SH DESCRIPTION
+The program
+.B optimise
+is one of a number of executable programs that forms part of a set of
+programs, collectively known as the
+.I Yagi-Uda project
+, which were designed for analysis and optimisation of Yagi-Uda antennas.
+.I optimise
+attempts to optimise the performance of a Yagi antenna for one or more
+parameters that are considered important, such as gain, F/B ratio, VSWR
+etc. It does this by randomly changing the lengths and positions, of one
+or more elements, then comparing the performance before and after the change.
+Any improvements are written to a new file called
+.I filename.bes
+where
+filename is the name of the antenna description file created by
+.I input
+or
+.I first
+.LP
+When Yagi's are designed on paper, or using this program, its possible that they will be almost
+impossible to build, if their performance depends too critically on the
+dimensions. To determine if this is the case with a design, we run optimise with just the options 't' and 'T'. These specify the tolerance with which you can build the antenna, expressed as a standard deviation in mm. In this case, instead
+of trying to optimise a poor design, optimise will calculate the minimum gain, maximum VSWR,
+and minimum FB ratio of a number of designs, all slightly different from the input file. 99.7% of the components
+lie within 3 SD of the mean, so if you think you can cut elements to with 1 mm 99.7% of the time,
+specify t0.33. If you can put them in the boom to within 3 mm 99.7% of the time, specify T1.
+.LP
+If while
+.I optimise
+is running using the methods that require weights to be attached to the gain,
+FB, SWR etc, it becomes apparent, the weights are not optimum, its possible to
+pause the program and re-adjust the weights. If a file with the name of
+.I changes
+is created, the program will pause, then request new weights are entered at
+the keyboard.
+.SH AVAILABILITY
+.SH OPTIONS
+.TP
+.B \-d
+Print the default values of all the configureable parameters to stdout. Typing this option with any
+option that changes a parameter (see below) will display the new value of the parameter, rather
+than the default.
+.TP
+.B \-h
+Print a help message.
+.TP
+.B \-v
+Print verbose status information.
+.TP
+.B \-w
+Instead of optimising at one fixed frequency (the design frequency), this directs the program to
+optimise at 3 separate frequencies (lowest, design and highest) then to average data at all 3. This
+option is better for wideband antenna. Note that the input impedance printed is at the design
+frequency, *not* averaged over 3 frequencies. Averaging an impedance, is likely to give a very
+misleading impression. The impedance averaged over 3 frequencies can be 50+i0 Ohms, even
+if the VSWR is very poor over all 3 frequencies, as the following 3 pieces of data show.
+.br
+Z=147 + j 300 SWR= 15.46:1
+.br
+Z=2 + j 100 SWR= 125:1
+.br
+Z=1 - j 400 SWR= 3250:1
+.br
+note in the above three cases, the average impedance is 50 + j 0, but
+average SWR is 1130:1.
+.TP
+.B \-O
+Over-optimisation allowed. By default, the program does not over-optimise a parameter. For example, an SWR of 1.01 is usually considered good enough and
+any change, as long as the SWR stayed good, typically below 1.1:1, would
+be allowed, even if the SWR rose. By default, FB's of 27 dB, VSWR's of 1.1 are
+acceptable. However, by using the
+.B \-O
+option, you can insist the program always improves things, no matter how good they are.
+.TP
+.TP
+.BI \-a Angular_stepsize
+When optimimising by trying to get a clean pattern, specifies the step size to
+use when looking for features in the pattern. If its set too small, the program runs slow. If its set too large, the program may miss features in the pattern, such as a sidelobe. Then the resulting antenna will have poor sidelobe performance, even though you think it will be good. The program attempts to calculate
+a sensible value, based on 1/10th the approximate 3 dB beamwidth, if you don't
+set.
+.TP
+.BI \-b boom_extension
+Generally speaking, the gain of a Yagi increases with boom length. Hence the optimiser would
+often give you a Yagi with a much longer boom than the input file. This may not be what you
+desire due to space restrictions. These long antennas often have high gain, but are very narrow in bandwidth. The default limits the antenna to 10x the original length, which
+means effectively there is no boom length limitation.
+You can adjust the percentage by setting
+.I boom_extension
+to whatever you wish.
+.I -b30
+will limit the boom to no more than 30% more than the original length.
+.TP
+.BI \-c cleanliness_of_pattern
+Specify the number of dB down on the peak gain to aim to get the pattern. Any
+antenna pattern cleaner than this will not effect the fitness, nor will it
+be considered any better when comparing to antenna designs. 20 dB seems reasonable, so the default is 20, but this may of course change if it's deceided too. Check the source code to be certain (see REASONABLE_SIDELOBE in yagi.h).
+.TP
+.BI \-e elements
+is an integer which specifies the type of elements that are changed in the optimisation cycle.
+Possible values are:
+.br
+.in +1.5
+1 - alter only the driven element(s) length (useful to bring to resonance)
+.br
+2 - alter only the driven element position. Don't change its length.
+.br
+4 - alter only the reflector length. The position is always at x=0.
+.br
+8 - alter only the director lengths. Don't change positions.
+.br
+16 - alter only the director positions. Don't change lengths.
+.br
+32 - randomly adjust one element length, then makes all other the same. Don't change the positions.
+.br
+64 - apply a linear taper to the lengths.
+.br
+128 - Set the driven element to a resonate length. It may/may-not be altered after the first run, depending on the whether or not '1' is invoked too. Eg -e128
+will make it resonate and keep it there forever. However '-e129' will bring to
+resonance, then alter to maximuse performance.
+.in -1.5
+The elements altered is made from a logical AND of the above, so for example to alter everything, except the driven element length, use -e30, since 2+4+8+16=30.
+The default is equivalent to
+.I -e31
+, which changes everything possible. Note the
+reflector position is *never* changed. It's always at x=0.
+.TP
+.TP
+.BI \-f FBratio
+When optimising an antenna, consider any FB ratio greater than
+.I FBratio
+dB to be equal to
+.I FBratio
+dB. This avoids optimising to a very high FB ratio, which is impracticable, as the bandwidth over
+which this FB ratio will be maintained is very small and mechanical considerations will prevent
+you from constructing it with such a high FB ratio anyway. If this was not prevented, you might
+just happen to get an antenna with 100 dB FB ratio, but poor gain and swr. Since by default all
+parameters must improve, the optimisation routine will most likely never being able to improve
+on the 100 dB FB ratio, so no improvement will result. Most people would prefer to get a few extra dB of gain,
+even if the FB ratio dropped to 30 dB.
+.TP
+.BI \-g GA_optimisation_method
+Use a genetic algorithm. With the genetic algorithm, the program does
+not take any account any of the initial lengths/positions of elements
+specified in the input file. Rather it works by initialising a
+number of different antenna, then computing a 'fitness' value for each.
+The fitness value can depend on the gain, FB, real part of the input impedance, reactive part of the input impedance, VSWR or the level of the sidelobes. The
+integer after the g tells the optimiser what to consider.
+-g1 Use gain
+.br
+-g2 Use FB
+.br
+-g4 Use R
+.br
+-g8 Use X
+.br
+-g16 Use the SWR
+.br
+-g32 Use the level of the sidelobes.
+.br
+
+You can use a logical AND of these, so for example -g49 will use a genetic algorithm, optimising for gain, swr and sidelobe level, since 1(gain)+16(SWR)+32(sidelobe level)=49.
+.TP
+.BI \-l percent
+is a parameter (floating point number) which specifies the maximum percentage
+change in the positions or lengths of an elements at each iteration. If the
+option is not used, it will be set internally at 10% for the first 25% of the
+iterations, 1% for the next 25%, 0.1% for the third 25% of the iterations and
+0.01% for the last 25% of the iterations. If set to a positive number x (eg optimise -l 0.3 145e10) then the percentage will be set at x% for 25% of iterations, x/10 for the next 25%, x/100 for the next 25 and x/1000 for the last 25%. If set to a negative number y (eg optimise -l -0.5 145e10) then the paramters will stay fixed at y% (in this example 0.5%) all the time.
+.TP
+.BI \-m min_offset-from_peak
+Sets the minimum angle in degrees offset from theta=90 degrees, where the
+side lobes start and the main lobe finishes. The higher the gain, the smaller
+it should be. It is set internally if not set on the command line.
+.TP
+.BI \-o optimisation_criteria
+.br
+.in +1.5
+1 - Assume better if the gain has increased.
+.br
+2 - Assume better if the front to back ratio has improved.
+.br
+4 - Assume better if the real part of the input impedance is closer to the
+value that the program was compiled for, or set using the '-Z' option.
+This will usually be 50 Ohms, but you may wish to set this to 12.5 Ohms if
+you use a 4:1 balun. Generally you can get higher gain from a Yagi if you
+allow the input impedance to fall, but of course feeding it becomes more
+difficult.
+.br
+8 - Assume better if the magnitude of the reactive component of the input impedance is lower
+(ie. the antenna is nearer resonance).
+.br
+16 - Assume better if the VSWR is lower.
+.br
+32 - Assume better if the level of all sidelobes is lower.
+.in -1.5
+The
+.I optimisation_criteria
+may be formed from a logical AND of these numbers, so for example choosing
+.I -o19
+will only consider a revised antenna better than the previous, if the SWR,
+gain and F/B ratio have all simultaneously improved.
+.br
+
+Clearly an antenna which originally had 12 dB gain and 1.01:1 VSWR but then
+changes to 20 dB gain @ 1.02:1 VSWR, would to most people be better, even
+though the VSWR has increased. By default,
+.I optimise
+only optimises to sensible maximums, so to not let the optimisation stall prematurely. By running
+.I optimise
+with no arguments, the program will list the limits of acceptability.
+These might be typically F/B ratio > 27 dB, VSWR < 1.1:1, magnitude of input
+reactance less than 5 Ohms and the real part of the input impedance within
+5 Ohms of Zo. Choosing
+.I -o19
+(1+2+16=19) will optimise for gain (since G=1), FB (since FB=2) and SWR (Since SWR=16), but would consider a higher gain and FB ratio antenna better than a
+previous one, even if the SWR rose, as long as it stayed
+below 1.1:1 (or as was set during compilation). The default behaviour (no options) is equivalent
+to
+.I -o37
+which optimiseas for gain(1), the real part of the input impedance(4) and sidelobes(32)
+but this may be changed at any time, so type
+.I optimise -d
+to check the current settings. If you insist on the program optimisang for the
+very best of all selected parameters, use the -O option too, but be warned the
+optimisation will probely stick once it gets one parameter really good.
+.TP
+.BI \-p population
+This determines the initial population used with the genetic
+algorithm.
+.TP
+.BI \-r resistance
+When optimising an antenna, consider any input resistance closer to Zo (usually 50 Ohms) than
+.I resistance
+Ohms to be acceptable. This avoids optimising to an input resistance too close to Zo, which is
+impracticable, as the bandwidth over which the input resistance could be maintained is very small
+and mechanical considerations will prevent you from constructing the antenna with such an ideal
+input resistance. If this was not prevented, you might just happen to get an antenna with an input
+resistance of 50.000001 Ohms, but poor gain, FB and possibly even a poor swr, if the
+antenna is well away from resonance. Since by default all parameters must improve, the
+optimisation routine will get most likely never being able to improve on the antenna, whereas
+we might be happier with a few more dB gain, if the input resistance went to 50.1 Ohms. It
+should be noted that the default optimisation routine never uses the input resistance directly (only
+VSWR), so this option cant be used without the '-o' option to optimise for other than the default
+parameters (gain, VSWR and FB ratio).
+.TP
+.BI \-s swr
+When optimising an antenna, consider any SWR less than
+.I swr
+to be equal to
+.I swr
+This avoids optimising to a very low swr, which is impracticable, as the bandwidth over which
+such a low swr could be maintained would be very small and mechanical considerations will
+prevent you from constructing such an antenna anyway. If this is was not prevented, you might
+just happen to get an antenna with an swr of 1.000000000001:1, but poor gain, FB ratio. Since
+by default all parameters must improve, the optimisation routine will most likely never being able
+to improve on the antenna, even though in practice you would like to get a few extra dB of gain
+if the SWR would rise to 1.02:1. The default was equivalent to
+.I -s1.1
+but run
+.I optimise -d
+to display this and any other defaults.
+.TP
+.BI \-t length_tolerance
+.I length_tolerance
+is the standard deviation in mm of the accuracy with which you can cut elements. Since 99.7%
+of elements will be with 3 standard deviations of the mean length (stats theory says this), set
+-t0.2 if virtually all (well 99.7%) of elements are within 3x0.2=0.6 mm of the correct length. This
+option *must* be used with the '-T' option and can't be used with any other options apart from
+'-Z', '-v' and '-d'.
+.TP
+.BI \-x reactance
+When optimising an antenna, consider any input reactance of less than
+.I reactance
+to be
+.I reactance.
+This avoids over optimising the reactance, at the expense of something else.
+.TP
+.BI \-A auto_gain
+When the
+.I auto_gain
+option is used. the program maximes the gain of the antenna (ignoring all other
+parameters such as SWR, FB ratio etc) by adjusting the length (not position)
+of one element only. -A-1 will maximuse the gain, by adjusting the length of
+the reflector, -A0 will maximise the gain by adjusting the length of the driven
+element. Its generally *not* a good idea to maximise the gain by adjusting the
+driven element, but the program lets you do it, but using the option -A0. Using
+-A1 will maximise gain by adjusting the length of the first director, -A2 the second director and so on, up to the last director. You must check carefully that the input impedance in particular does not fall to silly values if you use this option. On a yagi with many elements (> 10 or so), you can pretty safely maximise the 8th or more director, but doing it on the reflector, driven element or
+early directors often leads to silly input impedances - so beware!
+Note, no matter how many iterations you specify, this process is only done once.Its unlikely you will be able to do it again, without things going out of hand, but if you must do it, you must re-run 'optimise' again.
+.TP
+.BI \-C currents_similar
+If this option is used, where
+.I currents_similar
+is an integer, the program looks to make the
+currents in the last
+.I currents_similar
+elements as similar as possible. It computes the sum of the squares of the deviations of the absolute values of the element currents from the mean. If this falls, and the criteria specified with the -W option is also satisfied, the antenna is considered better. If
+.I
+currents_similar
+is three less than the number of directors, it tries to make the currents in the the directors (but ignoringing the first 3) all similar. If
+.I currents_similar
+is equal to the number of directors, it tries to make all the directors have similar currents. If
+.I currents_similar
+is one more than the number of directors, it tries to make all the directors and the reflector have similar currents. If
+.I currents_similar
+is equal to the total number of elements, then it fails with an error message.
+.TP
+.BI \-F weight_FB
+is the floating point number (default 1.0) specifying the weight to attach to
+the FB ratio of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-F' option is
+similar to the options -G, -P, -R, -S, -X (which specify weights for gain, pattern cleanliness, input resistance, SWR and input reactance).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness.
+However, unless you optimise for a high FB ratio with the -W option, then setting the -F option will have no effect. For example, setting the options -F2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the FB ratio from its default 1.0 to 2.5. If you are not optimising for FB ratio, the weight you attach to it is irrelavent.
+.TP
+.BI \-G weight_gain
+is the floating point number (default 1.0) specifying the weight to attach to
+the gain of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-G' option is
+similar to the options -F, -P, -R, -S, -X (which specify weights for FB ratio, pattern cleanliness, input resistance, SWR and input reactance).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness.
+However, unless you optimise for gain with the -W option, then setting the -G option will have no effect. For example, setting the options -G2.5 -W2 is a complete waste of time. There you have used the -W2 option to optimise only for FB ratio (see -W option section of man page) but have changed the weight of the gain from its default 1.0 to 2.5. If you are not optimising for gain, the weight you attach to it is irrelavent.
+.TP
+.BI \-K keep_for_tries
+.br
+.I keep_for_tries
+is the number of tries for the optimise to persist using the original data
+file as the starting point for optimisation. By default it is 1, which means the
+program immediately looks from a new position once a better one is found. It
+is theeoretically possible that this might result in a quick, but poor local maximum. If however,
+.I keep_for_tries
+is 1000, it will
+stay at a position for 1000 iterations after finding the last best result,
+before considering this to be a global optimum. Then it starts for the new
+position. In practice, I have found this option to make matters worst in most cases. It was added to avoid the local-minimum problem, but it appears the optimisation surface is pretty smooth, so it just slows the program, without gaining much. Anyway, it can stay as an option, but check the results with/without carefully before using extensively.
+.TP
+.BI \-P pattern_cleanlyiness
+is the floating point number (default 1.0) specifying the weight to attach to
+the cleanness of the antenna pattern when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-P' option is similar to the options -F, -G, -R, -S, -X (which specify weights for FB ratio, gain, input resistance, SWR and input reactance).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness.
+However, unless you optimise for a clean antenna pattern with the -W option, then setting the -P option will have no effect. For example, setting the options -P2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the pattern cleanliness from its default 1.0 to 2.5. If you are not optimising for a clean radiation pattern, the weight you attach to it is irrelavent.
+With appropiate use of the -W option (eg -W49 for gain, SWR and a clean pattern), the computer program finds the level of the most significant sidelobe, wherever it may be outside the main bean. It then optimises to reduce this. The -P option tells it how much weight to put on reducing this sidelobe.
+.TP
+.BI \-R weight_resistance
+is the floating point number (default 1.0) specifying the weight to attach to
+the obtaining an input resistance close to Zo on the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-R' option is similar to the options -F, -G, -P, -S, -X (which specify weights for FB, gain, pattern cleanliness, SWR and input reactance).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness.
+However, unless you optimise for an an input resistance close to Zo, with the -W option, then setting the -R option will have no effect. For example, setting the options -R2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the resistance from its default 1.0 to 2.5. If you are not optimising for an input resistance close to Zo, the weight you attach to it is irrelavent.
+.TP
+.BI \-S weight_swr
+is the floating point number (default 1.0) specifying the weight to attach to
+the SWR of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-S' option is
+similar to the options -F, -G, -P, -R, -X (which specify weights for FB, gain, pattern cleanliness, input resistance and input reactance).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c).

If you are not optimising for SWR, the weight you attach to it is irrelavent.
+.TP
+.BI \-T position_tolerance
+.I position_tolerance
+is the standard deviation in mm of the accuracy with which you can cut elements. Since 99.7%
+of elements will be with 3 standard deviations of the correct position (stats theory says this), set
+-T2 if virtually all (well 99.7%) of elements are within 3x2=6 mm of the correct position.This
+option *must* be used with the '-t' option and can't be used with any other options apart from
+'-Z', '-v' and '-d'.
+.TP
+.BI \-W Weighted_algorithm
+Try to get an antenna which is better according to a weighted combination of
+parameters, rather than require them all to improve. The integer specifies
+what to consider in the weighted parameters.
+.br
+W1 Gain.
+.br
+W2 FB
+.br
+W4 R
+.br
+W8 X
+.br
+W16 SWR
+.br
+W32 SIDE_LOBE
+.br
+You can logically AND these together, so for example -W3 will optimise using a weighted combination of gain and FB. -W49, will use a weighted combination of gain, swr and sidelobe leve, since 32+16+1=49.
+.TP
+.BI \-X weight_reactance
+is the floating point number (default 1.0) specifying the weight to attach to
+achieving a low input reactance on the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-X' option is similar to the options -F, G, -P, -R and -S (which specify weights for FB ratio, gain, pattern cleanliness, input resistance, and SWR).
+When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness.
+However, unless you optimise for a low input reactance with the -W option, then setting the -X option will have no effect. For example, setting the options -X2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the reactiance from its default 1.0 to 2.5. If you are not optimising for a low input reactance, the weight you attach to it is irrelavent.
+.TP
+.BI \-Z Zo
+.br
+.I Zo
+is the characteristic impedance used when evaluating the VSWR, reflection coefficient and other
+similar calculations. The optimiser usually tries to bring the input impedance of the antenna to
+this value. It is set by default to 50 Ohms, so the default is equivalent to
+.I -Z50
+but may be set to any positive number. Set to 12.5 Ohms if you are going to feed the antenna
+with a 4:1 balun. Generally speaking, the gain of a Yagi
+can be higher for low input impedances, but of course such antennas are
+more difficult to feed.
+.TP
+.I filename
+This is the name of the file containing the antenna description. It is expected
+to be in a format created by either
+.I input
+or
+.I first
+- two other programs in the
+.I Yagi-Uda project.
+This is an ASCII text file.
+.TP
+.I iterations
+is an integer specifying the number of iterations for the optimiser to perform to try to get the best
+antenna. Time will limit the number you choose. 1000 iterations of a 1ele yagi takes about 5
+seconds, a 6ele approximately 60 seconds, an 11 element 350 seconds, a 20 element 1030
+seconds, a 33ele 2440 seconds, a 50element 5400 seconds, 100ele 21320 seconds all on an old
+25MHz 486 PC with no external cache.
+When using the
+.I -A
+option the
+.I iterations
+is automatically set internally so only one attempt is
+made.
+When using the '-t' and '-T' options,
+.I iterations
+specifies the number of iterations to attempt to get a poorer design, to check the sensitivity of
+the design to small manufacturing tolerances.
+.SH EXAMPLES
+Here are a number of examples of using
+.I optimise.
+.PP
+1) optimise 5ele 1000
+.PP
+Here the file 5ele will be optimised using the default system for 1000
+iterations. The default might typically require gain, FB and SWR to
+all improve, but this may be changed at any time. In any case, the
+program tells you what its optimising for. By default the program will
+only optimise to the selected parameters are good, not over-optimising any
+one at the detrement of the others.
+
+2) optimise -b30 -f50 -s2 5ele 1000
+.PP
+This is similar to above, but the boom can not extend by more than 30%
+from its original length, FB ratios above 50 dB are considered acceptable,
+as are SWR's less than 2:1. The optimised resultant antenna is likely to have
+better FB ratio, but poorer SWR than in (1) above.
+
+3) optimise -o1 5ele 1000
+.PP
+This will simply optimise 5ele for maximum forward gain. The resultant
+antenna may have a poor FB ratio and is likely to have an unacceptably
+low input impedance and hence high VSWR. This is not a very sensible
+method of optimisation.
+
+4) optimise -W49 -l7 5ele 10000
+.PP
+This will optimise the file 5ele using for 10000 iterations. It will
+require that the weighted performance of the antenna in three important
+parameters (gain, sidelobe level and SWR) improves from one design to the
+next. One or two parameters can actually get worst from one design to
+the next, but the weighted performance is better. The positions of the elements or lengths of
+elements will not change by more than 7% in each iteration.
+.PP
+5) optimise -g -S30 -G50 -F20 -p1500 5ele 10000
+.PP
+This will optimise the file 5ele using a genetic algorithm. 1500 antennas will be randomly
+designed. The performance of each of these will measured using a 'fitness' function, weighted
+30% to SWR, 50% to gain and 20% to FB ratio. The probability of breading from a pair of
+antennas is proportional to the fitness function.
+.PP
+6) optimise -w atv_antenna 10000
+.PP
+This will optimise the file atv_antenna for a best average performance over a wide band. The progrram calculates the gain, FB and SWR at three frequencies, then computes an average (mean) performance of the antenna over the band. N iterations will take 3x as long to execute as N iterations on the same antenna without the '-w' option.
+.PP
+7) optimise -t0.1 -T1 good_design 100
+.PP
+This will take the file good_design and make 100 different antennas from it,
+to simulate the effects of building tolerances. Each element is assumed to be cut so that the mean
+error of all elements is 0 mm, but a standard deviation of 0.1 mm, so 68.4% of element lengths
+are within 0.1 mm, 95.4% within 0.2 mm and 99.7% with in 0.3 mm. The accuracy of placing
+elements along the boom is much lower, so here we have specified a standard deviation of
+1.0 mm, so 68.6% of elements are placed within 1 mm of the correct position, 95.4% within 2 mm
+of the correct position etc. The program will report the *worst* performances achieved. If the
+performance dips too mush, then you either need to build them better, or get a design that's less critical!
+
+.SH STOPPING
+.I Optimise
+will stop after the number of iterations specified in the parameter
+.I iterations.
+It will also stop if a file
+.I stop
+exits in the current directory of the executable
+.I optimise
+This file can of course only be created using a multi-tasking operating
+system such as Unix. It is *not* advisable to stop the program by
+hitting the DEL key (Unix) or CONTROL-C (DOS), as one of the files may
+be open at the time, resulting in an empty file. Files are not open for
+any longer than necessary (they are closed immediately after writing to
+them), so this is not a likely occurrence, but can still occur.
+.SH LIMITATIONS
+I'm not aware of any limitations, apart from that filenames, including full
+path, can't exceed 90 characters.
+.SH FILES
+.nf
+filename Antenna description, created by input or first.
+filename.up Update file, listing achievements of optimise.
+filename.bes Best file, containing the best design to date.
+changes File that causes the program to pause to re-adjust weights.
+stop File that stops optimisation process.
+.br
+.fi
+.SH "SEE ALSO"
+first(1), input(1), output(1), yagi(1), first(5), input(5) output(5) and optimise(5).
+
+.SH PLATFORMS
+Both DOS and Unix versions have been built. The DOS version as
+distributed requires a 386 PC with a 387 maths coprocessor.
+
+Although I have altered the source to make it more compatible with DOS (reduced file name
+lengths etc), my wish is to build a decent program, rather than fit the program to an outdated
+operating system. If there is a *good* reason to use code that is incompatible with DOS, this will
+be done.
+.br
+Since
+.I optimise
+takes a while to optimise an antenna (I've optimised one design for a week), it is obviously
+more sensible to build this program under a multi-tasking operating system, as otherwise a PC
+can be tied up for days.
+.SH BUGS
+Bugs should be reported to
+.BR david.kirkby at onetel.net .
+Bugs tend actually to be fixed if they can be isolated, so it is in your
+interest to report them in such a way that they can be easily reproduced.
+
+The program will dump core (crash) if asked to optimise a 1ele beam, without any arguments.
+This is because a 1ele beam has no parasitic elements and by default the program only changes
+parasitic elements.
+
+Some of the options are not checked for sensible values, although most are
+now checked and report if they are out of range.
+
+If the user specifies very large manufacturing errors using the '-t' and '-T'
+options, its possible for elements to overlap or for element lengths to
+become negative. This will cause numerical errors. Any reasonable values
+will not cause this.
+
+
+On long Yagi's (50 elements) optimise can go a bit silly. It can optimise
+say a 1296MHz Yagi to get 20 dB at 1296 MHz, but less than 0 dB at only 1 MHz
+away. Needs some thought!
+
+The level of the sidelobes is not computed with the GA or some other optimisation types. This will be corrected later.
+
+All those I don't know about.

+.SH DESCRIPTION
+The program
+.I output
+is one of a number of executable programs that forms part of a set of
+programs, collectively known as the
+.I Yagi-Uda project
+, which were designed for analysis and optimisation of Yagi-Uda antennas.
+.I output
+calculates the gain, FB ratio, input impedance etc etc of an antenna that was described by the
+program
+.I input
+or
+.I first
+and has had the element currents calculated with the program
+.I yagi
+The data about the forward gain, VSWR, FB ratio, input impedance etc is written to a file
+.I filename.dat
+Angular data, giving the variation of gain with theta and phi is put into a file
+.I filename.gai
+.br
+Sometimes the program fails to find the 3dB bandwidths in the E and H planes,
+and bombs out with a 'zbrent' error. This can occur if:
+.br
+(1) The antenna has an almost isotropic pattern, in which case its never 3dB
+down, so the 3dB point is undefined.
+.br
+(2) The 3dB point is outside the assumed angular range.
+You then have to either:
+.br
+(a) Calculate with the -e option, which avoids calculation of the 3dB E-plane beamwidth or
+.br
+(b) Do (a) above, then find approximately where the 3dB point is (from the .gai file -see later), then set
+options -E and -H so the program calculates them properly.
+.LP
+
+
+.br
+The DOS .EXE files as distributed require a 387 maths coprocessor to be
+present and will not run without it. A 486, Pentium, and I assume later
+processors of this series will run it without any extra hardware. The DOS files are no longer being
+maintained, so are out of sync with the latest source.
+.SH OPTIONS
+.TP
+.B \-c
+Calculate the maximum level of any sidelobe - not just the rear on as the
+FB ratio tells us. If the sidelobe and FB ratio are equal, it means the
+biggest sidelobe is the rear one. If the Sidelobe is less than the FB
+ratio, then another lobe is more significant. Look in the '.gai' file (see
+below) to see where it is. This option slows the program quite a bit.
+.TP
+.B \-e
+Suppress calculation of the 3dB E-plane bandwidth. This is sometimes necessary if the programme is
+unable to find the 3 dB beamwidth, to prevent an error occuring.
+.TP
+.B \-h
+Suppress calculation of the 3dB H-plane bandwidth. This is sometimes necessary if the programme is
+unable to find the 3 dB beamwidth, to prevent an error occuring.
+.TP
+.B \-p
+Put data into a file filename.freq for reading into gnuplot, and a commmand file filename.gc for
+gnuplot to use. (run 'output -p filename' then 'gnuplot filename.gc' )
+.TP
+.B \-s
+Suppress all diagnostic output. By default, the program print the percentage of the job completed.
+.TP
+.BI \-E E_max
+When the program computes the E-plane 3dB beamwidth, it assumes the antenna pattern is 3dB down somewhere in the range 90 to Emax, where E_max is by default 179 degrees. This can fail if it is never 3dB down in the range, or if it happened to go 3dB down in two or more points. You can change E_max, if you need to, but
+rarely if every should need to. I've never seen a failure here, but are guarding against one. If you dont want the pattern, use the -e option instead, which skips it. See also '-H' below.
+.TP
+.BI \-H H_max
+When the program computes the H-plane 3dB beamwidth, it assumes the antenna pattern is 3dB down somewhere in the range 0 to Hmax, where H_max is by defualt 60 degrees. This can fail if it is never 3dB down in the range, or if it happended to go 3dB down in two or more points. Also, if it goes more than 3dB down, but that starts to come up again. You can change H_max, if you need to, as
+failures do occasionally occur. If you dont want the pattern use -h option instead, which will skip it.
+.br
+An obvious example of an antenna where you cant find the 3dB bandwidth for the H-plane is the 1ele dipole. The radiation is symmetrical about its axis, so the level is the same everywhere in the H plane. The program automatically avoids calculating it for a 1 ele beam.
+
+.TP
+.BI \-Z Zo
+Zo is the characteristic impedance used when calculating the VSWR. By default it's 50 Ohms, but can be changed to any real, positive value.
+
+.TP
+.I \ filename

+optimise \- output data file formats
+.SH DESCRIPTION
+This manual page describes the output formats of the files created by the
+.IR Yagi-Uda
+project's
+.IR optimise
+program. The input files required for optimise are plain ASCII which can be generated by
+.IR input
+or
+.IR first.
+or may be generated manually with a text editor, if care is used. The format required by optimise is described in input(5). Optimise's output files, which have the .bes extension are the same format as the input files and are again obviously described by input(5).
+
+.SH Example of a .up file.
+
+The .up file list the improvements made by optimise to an antenna
+design. Starting from the original design, the file is appended each time a new better design is found. Here is an example, where the final line is the performance of the 4 element beam with the .dat file shown earlier.

+.SH What is what in the .dat file
+The f(MHz) column is the frequency (MHz) at which the data is evaluated at.
+.br
+The E(deg) column is the approximate 3dB E-plane bandwidth calculated to the nearest 0.1 degree.
+.br
+The H(deg) column is the approximate 3dB H-plane bandwidth calculated to the nearest 0.1 degree.
+.br
+The (R) column is the input resistance in Ohms.
+.br
+The (jX) column is the input reactance in Ohms.
+.br
+The (VSWR) column is the input VSWR, usually refered to a 50 Ohm input, but this may be changed.
+.br
+The Gain (dBi) column is the gain at theta=90 degrees, which is the forward direction of the beam. It is possible that a higher gain occurs at other than 90 degrees, but this is not taken into account. The antenna is seriously at fault if this occurs.
+.br
+The FB(dB) column is the front to back ratio in dB.
+.br
+The Sidelobes(dB) column is the minimum level in dB down from the peak gain of any sidelobe. This is not calculated unless the '-c' option is used, and then only on some optimisation techniques.
+

+.br
+
+.SH What is what in the .gai file
+The f(MHz) column is the frequency in MHz.
+.br
+The theta column is the angle theta, for which the next two columns refer.
+.br
+The gain-E(dBi) is the gain at theta, relative to an isotropic radiator.
+This is the E-plane gain. Hence at the peak (theta), this gives the
+peak forward gain.
+.br
+The G(E)-peak is the gain at theta, relative to the peak gain. Hence
+at the peak (theta=90 degrees), this is zero.
+.br
+The phi column has nothing to do with the previous 3 columns. It is the angle
+for which the next two columns refer.
+.br
+The gain-H(dBi) is the gain at phi, relative to an isotropic radiator.
+This is the H-plane gain. Hence at the peak (phi=0), this gives the
+peak forward gain.
+.br
+The G(H)-peak is the gain at phi, relative to the peak gain. Hence
+at the peak (phi=0 degrees), this is zero.
+.br

+.TH YAGI 5 "24th October 2000" "Yagi version 1.16"
+.SH NAME
+yagi \- yagi binary output format
+.SH DESCRIPTION
+This manual page describes the output format of the file created by the
+.IR Yagi-Uda
+project's
+.IR yagi
+program. The file is a binary file with a header of 100 bytes. The
+header consists of:
+
+
+.nf
+.ul
+offset(bytes) information data-type
+
+0 elements int
+4 driven int
+8 parasitic int
+12 min_frequency double
+20 max_frequency double
+28 design frequency double
+36 step_frequency double
+44 angular_step double
+52 0 double
+. . .
+. . .
+. . .
+92 0 double
+
+Following the header, there starts the coordinates(x,y,l) of each
+element and the voltage applied to each element. Then we write
+the element currents one after the other, at each frequency.
+Hence the element currents will be written 12,000 times with a
+3 element yagi analysed at 4,000 different frequencies. All complex
+data is stored in a structure of type fcomplex, defined as:
+
+struct fcomplex {double real, double imaginary};
+
+.ul
+offset(bytes) information data-type
+
+100 x1 double /* coordinates */
+108 y1 double
+116 l1 double
+100+(n-1)*24 x_n double
+100+(n-1)*24+8 y_n double
+100+(n-1)*24+16 l_n double
+.............. Repeated for each element.
+100+24*elements Voltage1 fcomplex /* voltage */
+100+24*elements+(n-1)*16 Voltage_n fcomplex
+.............. Repeated for each element n at each frequency step f.
+100+40*elements Current1 at f1 fcomplex /* current */
+100+40*elements+(n-1)*16 Current_n at f1 fcomplex
+
+100+56*elements Current at f2 fcomplex
+100+40*elements+(n-1)*16 Current_n at f2 fcomplex
