Paradan Radio Dual Antenna Disconnectors

Paradan Radio Dual Antenna Disconnectors reduce the chance of station damage from lightning pulses. The Dual Antenna Disconnector automatically disconnects and isolates any radio equipped with two antenna ports—and it grounds both antenna SO-239 coaxial connectors. The two radio SO-239 connectors may also be used for two separate transceivers or receivers. The Dual Antenna Disconnector is excellent for protecting remote stations from lightning pulse damage.

The Dual Antenna Disconnector prevents static-discharge, surges, and lightning-pulse effects from damaging your radio and associated equipment. When the transceiver is turned OFF, both antenna coax center conductors and shields are shorted together and grounded—and both coax center conductors and coax shields are disconnected from the radio. When the transceiver is powered ON, the Disconnector re-connects both coaxial cables for normal operating. Power for the Disconnector can be supplied by either the transceiver's auxiliary DC power output or by the station power supply that is turned off when not operating. For stations where the power supply is always left on, the Radio ON Sensor unit tells the Disconnector to reconnect coaxial cable when the radio is turned on.

For correct operation the Dual Antenna Disconnector requires a good earth ground. The unit is supplied with a ground wire ring terminal, four wire splice connectors, and a Powerpole® connector pair.
