INPUT(5) File Formats Manual INPUT(5)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.

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 elements, 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 for-
mat 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 coprocessor.

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).
