I own an Icom 746 (non-Pro) for my base transceiver. The 746 has two HF 160 - 6 meter antenna ports and one 2-meter vhf port. I would like to find a triplexer which would allow me to use one feed line between the transceiver and three antennas, a Cushcraft R-8 40-6 meter vertical, a horizontal loop with an SGC-237 antenna coupler for 160 - 6 meters, and a Diamond 2-meter vertical antenna. Do you know of a triplexer with two 160 - 6 meter ports and one 2-meter port? Alternatively, if no triplexer exists for this configuration, what other options do I have with this transceiver and antenna collection?

A triplexer routes signals simultaneously to three ports based on frequency—thus, the outputs of all three ports must be different frequency ranges.

What you may want is a pair of diplexers to separate the 2M and HF/6M signals at either end of the single feedline. You will need a remote antenna switch to switch between the two multiband antennas.
