OPEK CX-201U - 2-Way Coaxial Antenna Switch - SO-239
The OPEK CX-201U Coax Switch utilizes a center ground tap that keeps the unused port terminal grounded when not in use. It has Type UHF-Female (SO-239) coaxial connectors and better than 50dB isolation.

I purchased this switch in conjunction with some PL259-SO239 connectors so that I could permanently rig my main antenna and an emergency antenna to the VHF radio on my boat. In this way, if the primary antenna ( tied into the "A" channel )fails offshore for any reason, re-establishing voice radio transmissions is simply a matter of turning the switch to the "B" channel.
The switch is installed on the back of the instrument panel bulkhead inside the cabin, so there are no worries about long-term salt-water exposure, although I think that waterproofing / corrosion-proofing such a switch if need be would not be too difficult. The switch itself is very sturdy and well-made, with brazed solid copper contacts and a heavy-duty powder-coated casing, so it should last a long time even under severe use.
The service and pricing at ARS was excellent, as was component availability. I will definitely be sourcing more radio equipment from them in the future.
The results have been excellent so far

This is a perfect way for me to share an Antenna between two mobile Transceivers.
