Introduction
The Yagi-Uda project is a set of programmes for designing, analysing and optimising Yagi-Uda antennas, such as shown below.
The programmes were developed by Dr. David Kirkby (G8WRB).
Several programmes are included:
A few other programmes that were developed for test
purposes are included, but there are not needed for normal use.

Designing an antenna.
Several stages are needed to design a Yagi-Uda antenna using these tools
1) What you do first depends on whether you have an antenna design you wish to analyse (like one from a book) or if you want to design one using the tools in the Yagi-Uda project.
a) If you have an antenna you wish to analyse, use input to specify it in the form suitable for the programmes in the Yagi-Uda project.
OR
b) Assuming you don't know exactly what you wish to analyse, you can let the programme first design you an antenna. It wont be good, but it is sufficiently close to optimal that it can be optimised with optimise.
2) Calculate the currents in the antenna, using the programme yagi
3) Calculate the performance of the antenna using the programme output.
4) Look at the files created by output (filename.dat and filename.gai) to see how good the antenna is.
5) You may only want to do 1-4 above, but you will probably want to optimise the antenna, using optimise.
For more informaiton
The programmes have on-line man pages, but there are
available in html format too. There were converted to html format
using the programme man2html
There are also some files describing the file formats.
