If you're worried about burning out the receiver front end, why not test 
it?  Add a 20 dB (or more) attenuator in front of the receiver and have 
your neighbor try transmitting on all bands and antennas.  The K3 S 
meter is pretty accurate.  Just add 20 dB to the reading to see how much 
RF is coming down the coax.
