As long as you are using 1 antenna system for TX and another antenna system for RX then that will work without a duplexer, if you follow a few guidelines. First, you have to use gain antennas (not 1/4 waves verticals). Unity gain, omni-directional antennas (like 1/4 wave verticals) radiate in all directions equally and you cannot effectively isolate one from the other. Provided you have 2 antennas with some gain, I would recommend at least 9dBi, you will need enough tower or mast to vertically seperate the antennas by 10 or 15 feet. If you are using yagi type antennas, the same rules apply.
