I build all my RX antennas with a relay in the transformer
box. The relay, which is powered through the coax, opens
the loop and shorts out the input of the transformer
whenever the station is switched off or when transmitting.
That way I get RX protection during transmit and during
thunderstorms (when the station power is off).
