Antenna reception theory
Asimov wrote:
. . . RH The definition looks OK to me. The reason the signal is not the same RH as the microvolts-per-meter even when the antenna is a 1-meter length RH of wire with just the right slant is because the induced voltage gets RH divided between the antenna and its load (the receiver). Not only that, but also this: the antenna rebroadcasts half of the intercepted energy. But voltage isn't energy. Or power. Roy Lewallen, W7EL |
