NAME
     input - YagiUda project antenna defining program

SYNOPSIS
     input [ - h ]

DESCRIPTION
     The program input is one of a number of executable  programs
     that  forms part of a set of programs, collectively known as
     the Yagi-Uda project , which were designed for analysis  and
     optimisation  of  YagiUda  antennas. input is an interactive
     program, that asks the user for  information  about  a  Yagi
     design,  such  as position of elements, spacing between ele-
     ments, frequency span of interest and a filename to save the
     data  to.   input then writes this information into an ASCII
     file, which can be read by yagi  or  optimise  The  file  is
     ASCII  and  it's  format  is easily understood by inspection
     (there are comments printed in it), so it can  if  necessary
     be edited manually.

     After running input and specifying a filename  (for  example
     144e10)  you  should  then  type yagi 144e10 and then output
     144e10 and optionally optimise 144e10

OPTIONS
     -h   Print a help message.

LIMITATIONS
     None known.

FILES
     filename         ASCII data file in which design is put.

PLATFORMS
     Both DOS and Unix versions have been built. The DOS  version
     as  distributed requires a 386 PC with a 387 maths coproces-
     sor.

COPYING
     This program is public domain,  but 4 of the source routines
     are copyrighted.  In order to build, you will need to obtain
     the routines cisi.c, complex.c, lubksb.c  and  ludcmp.c  for
     the  book 'Numerical Recipes in C', 2nd edition, by Press et
     al, Cambridge University Press, (1992).

     You may copy the sources (less those 4) and  executables  to
     anyone  you wish in the usual unix tradition, as long as you
     let people know they can get the sources and don't make  any
     profit from it. You may charge a *small* distribution fee.

AUTHORS
     Dave Kirkby G8WRB (davek@medphys.ucl.ac.uk).  with help with
     in    converting    to    DOS/PC    from   Joe   Mack   NA3T

BUGS
     Bugs should be reported to
     davek@medphys.ucl.ac.uk.
     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 a mistake is made  during  inputting  of  data  (such  as
     entering an incorrect length), it is not possible to go back
     and correct this. You should make a note of the  error,  and
     edit  the  ASCII  text file with a text editor (vi, DOS edit
     etc).
