Drew, Receive only antennas can really extract wanted signals out of a mess of local electrical noise.
To be effective they need to have minimal coupling to the transmit antenna, otherwise all the trash collected on the main antenna appears on the receive antenna signal. This means a reasonable distance between the two antennas which also helps to prevent damage to the receiver front end, but with high RF power care is needed. A lot of receive antennas have low output so use a 20dB or so pre-amp. It is possible that this could be killed with RF, long before the rig suffers.
