NAME

     input - input data file format

DESCRIPTION

     This manual page describes the output  format  of  the  file
     created by the Yagi-Uda project input or first programs. The
     file is  an  ASCII  file,  so  can  be  edited  manually  if
     required.  It  is  read  by  yagi  or optimise.  The program
     optimise also creates the same file format.

     A typical file, for an antenna designed for the 2m amateur band (144-146
     MHz) might be as shown below. Note:
     1) Reflector is at position 0.0
     2) All elements lengths/positions are in m.
