NAME

     input - Yagi-Uda 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  Yagi-Uda 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.


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.

     Bugs should be reported to
     david.kirkby@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 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).
