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.
