WebRadio Mathematics - ARRL - Home Webpassing radio wave: A = πr2 where r is the radius, half of the diameter of the dish. If we replace a dish antenna with a much larger one, the greater aperture of the larger is capturing much more of the passing radio wave, so larger dish has more gain than the smaller one. If we do a little geometry, we find that the gain is proportional to the

Webexample. In the typical ham station setup, a transmitter is connected to a feed line, which is then connected to the antenna. When you key the transmitter, it develops a radio fre-quency (RF) voltage on the transmission line input. The voltage travels down the feed line to the antenna at the other end and is called the forward wave.
