'Antenna Disconnect', produced by Paradan (USA) is a safety dish for antenna coasic cables. As soon as the station is deactivated, the antenna is completely insulated from the radio. You no longer need to unscrew coasial connectors when a thunderstorm occurs.
Especially for remotely controlled stations, this is a critical feature that saves the entire radio station.
The Disconnect Antenna not only cuts the central conductor of the coasialine line, but also the outer screen. The antenna side of the lad is permanently connected to an over-voltage protection, which cuts voltage spikes all the time, even when the station is in use. The relay is activated by an auxiliary radio output; As soon as the transceiver is turned on, the antenna is connected to the radio. If the auxiliary output is not available, the relay can use the same power as the radio: as soon as the common power is removed, the entire station shuts down and the antenna is disconnected.
The disconnect antenna insertion loss is only 0.05 dB at 29 MHz. Even at 144 MHz it is only 1 dB. The maximum power is 1500 W. A green LED shows the operational status of the field. Switching voltage is provided via a two-conductor DC cable with RCA connector.
