I was asking about receiving, not realizing it was any different than transmitting. I thought a poorly tuned antenna would give a poor SNR for receiving and not transmit as well when transmitting (though I don't know the metric for that).
When I said an FM antenna being a wire, I was thinking of a home stereo and an antenna like this:
With those clarifications out of the way, the example was very helpful. I can't say I understand all the theory, but maybe I can take a crack at explaining what I think to be the case and we can iterate?
The waves come in and hit the antenna, inducing a current. In the middle section, it's blocked, but it gets in above and that's the resonant frequency, so the signal will be nice and strong. Below the double shield, the cable is still shielded, so it gets minimal interference on that segment.
I know my terminology is probably wrong here, but is that the gist of it?
