If you have separate uplink and downlink antennas, both with independently switched polarity, couldn't you tune the polarity on the downlink to best reception, and then transmit while listening and simultaneously flipping polarity on the uplink? You'd have to switch a couple of times quickly to be sure you weren't experiencing a downlink fade. Just a thought.

Again, even in full duplex how do you distinguish between a
non-matchinguplink vs non-matching downlink? You only "hear" the downlink!
