Project: HGG - Antenna Design
There's also a nice collection of satellite antenna designs at dxzone.
Findings about Antenna Design
Random facts about antennas we found out or read about. Need to be put into an article and into context.
Why is usually a 1/2 lambda antenna used?
Imagine a Sine wave. Imagine a half wavelength starting at PI/2. It goes until 3/4 * PI. That means you have the beginning where the value of the sine is max and the end where it is minimal. That means your difference is maximized. For a wave - it's the same. Thus by using lambda / half antennas you can maximize the output-level.
To think about: Does an antenna cause a phase shift? (I think it does).
