# input(1)

Yagi-Uda project antenna defining program

## 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 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 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 coprocessor.

## AUTHORS

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).
