	RAP-1	Receiver Antenna Protector Install this little box between your receive antenna and your radio's receive antenna input to protect your expensive radio from the RF that your receive antenna picks up from your tansmit antenna.

An internal relay completely removes the receive antenna (center AND ground) and places a 50 ohm resistor across your receiver terminals during transmit. Needs 12 VDC and a keying signal to ground from your radio (can also be used with an amplifier keying as well). We suggest 2 RCA cables (below)	$44.95
