Mike, If your rig does not have an RX only port, you can use a rx/tx relay. There are a number of commercial units available. One (with which I have no connection whatsoever) is made by KD9SV and is available through Radioware.
It has an rx protection circuit (to keep you from blowing out your front end), a dual band (160-80 meter) variable gain pre-amplifier and a four-position antenna switch in one box. The four position antenna switch will allow you to select four different receive antennas while giving you front-end protection and a variable dual band pre-amp. You can also by pass the unit and use the transmit antenna when you are operating on the higher bands or if you want to use the low band transmitting antenna. New Improved Solid State Switching design. Again, there are a number of other units out there, or you can build one.
