I'll email my grandad & see if he recalls any more details. He was involved in AM radio transmitter design for a while and had a few oddball stories like this.

If your close enough to a powerful enough transmitter, an antenna may produce enough wattage (volts*amps) to run some small lighting (LED's?) but you won't light up a house this way. This is how the old crystal diode radios work without an external power source. The radio waves actually generate a small current in the coiled antenna.
