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).
