Antenna disconnect switch 2 antennas

'Antenna Disconnect', is manufactured by Paradan (USA) & is a safety relay for antenna cables.
When the radio is switched off, the antenna becomes completely isolated from the radio.

Especially for remotely controlled stations, this is a critical feature that can save the radio.

The antenna switch not only breaks the center conductor but also the screen.
The antenna side of the relay is permanently connected to a surge protector, which provides a good surge protection.

The relay is activated from external 10-18v or if the transceiver has external 12v output.

The loss over the relay is only 0.05 dB at 29 MHz & at 144 MHz it is only 1 dB.
Max Power 1500 W on HF & 1000W at 144MHz.
A green LED shows the relay's operating mode.
