We have relatively low power losses in copper wire at 60 Hz, but when you get up into the MHz range of frequencies, we start radiating and losing power and we switch from wire to something like coaxial cable or heliax and call it transmission line instead. We ground the outer conductor (shield) to "contain" the signal in the center conductor... Do I have the basics of that right?
But anyway, my question is at what frequency range does our ordinary wire start turning into an antenna and start radiating?
Any good sources on this?
