Good dependable switch tested up to VHF on field day. I use two of these to switch to 40m and 15m to keep signals separated from adjacent stations so it has good signal separation (isolation) at HF.
The first thing I did when I received the switch was to open the back. What I found was solid, quality construction! I use it in reverse mode feeding one antenna with two transceivers. I highly recommend this switch and AmericanRadioSupply. com
I have a vertical and horizontal antenna feeding the switch, makes it easy to select which one connects to my transceiver.
This antenna switch works great. I have 2 HF Antenna's connected to it. Very well built.
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.
Great switch works. well great. construction.
