Remember, a receiver works on the voltage difference between the antenna

I thought it worked on resonance.
Resonance is one of many things that goes into receiving signals,
but when you come right down to it the receiver is nothing more
than a device which processes the voltage (or current) fed it from
an antenna. You use it to select one of many signals (using
resonance), amplify the heck out of it and extract the information
from the result.
What's that got to do with a current flowing to ground?
