| Jul 12, 2017 at 23:41 | comment | added | Harry Svensson | When the antenna receives a signal that it resonates to, then current will flow out of one end and in from the other. It only resonates to AC signal. A good way to think about it is as if you have an AC signal connected to a capacitor, the capacitor end that goes somewhere will push and pull current. | |
