## 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).
