You will not get enough isolation between antennas to prevent preamp damage without a relay on RX...unless the antennas are very widely separated...not too practical.

But the ARRL is stupid with this contest, as its 50-1296 MHz on 2 weekends, so what band are we going to operate and when....so activity can be dispersed accross the bands.
