I understand things like waveforms and frequencies quite well, but I can't find something that will adequately explain how we get the radio waves in the air and get it back out. In a receiver, does the antenna receive a tiny voltage that is amplified to be useful? And how do we make a line voltage or waveform come out of an antenna? My brain still only thinks that it would act like an open circuit, but it obviously doesn't. What part of a radio transmitter makes it able to turn voltage signals into radio waves?
