Dual Antenna Disconnector
Reduce the chance of station damage from lightning surges.
The Dual Antenna Disconnector automatically disconnects two antennas from your radio and grounds both antennas. The Disconnector prevents static-discharge, surges, and lightning-strike effects from damaging your radio and associated equipment.When the transceiver is turned OFF, the antennas’ signal and ground wires are shorted together and grounded, and both the coax centers and coax shields are disconnected from the radio.When the transceiver is powered ON, the Disconnector re-connects both antennas for normal operating. Power for the Disconnector comes from the transceiver’s auxiliary power socket. Or connect it to your power supply that you turn off when not operating . For those radios without an auxiliary power socket and you leave your power supply on , a separate unit, the Radio ON Sensor unit is used to sense if the radio is turned on. For correct operation the Disconnector requires a good earth type ground. The unit comes with a Ring Terminal, four Barrel Connectors, and a Powerpole® pair. The Dual Antenna Disconnector is excellent for protecting remote stations from lightning surge.

When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away.
