Radio transmitters and receivers?
I don't really know much about electronics or radio, but here is how I understand how radio transmission works and I got a couple of questions. Say we have an LC circuit, since the current in it is oscilating, the wires emit EM waves, if you attach a single wire to that, it will become like an antenna and there will be alternating current in it as well, right? Now it emits waves at some frequency and then you have another antenna, also a single wire that will pick up the signal and then you have some sort of an amplifier etc
If that's correct then please answer this question:
What happens if you connect the two antennae by a wire? Would you still get the same signal at the receiver, only perhaps stronger or smth?
Alright, if the signal will be much stronger, I can just make the output signal weaker and not amplify it too much so that it's not overwhelmingly strong.
I'm asking this basically because want to know it it's possible to transmit a signal through a single wire.
You could connect a transmitting antenna to a receiving antenna, but the signal strength would be so strong that it would overwhelm the receiver, and you probably wouldn't receive anything intelligible. (That might not be true for some radio transmission technologies, like FM, but would probably be true for AM.) Since the loss between transmitter and receiver is insignificant when compared to the loss over the airwaves, the signal strength would be orders of magnitude higher than expected.
