Dual Antenna Disconnector

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.
