WebAmerican Radio Relay League 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
