Paradan Radio Presents the Antenna Disconnect

  • Reduce the chance of station damage from lightning
  • The Antenna Disconnect automatically disconnects the antenna from your radio and grounds the antenna
  • It prevents static-discharge, surges, and lightning-strike effects from damaging your radio and associated equipment
  • The Antenna Disconnect Actuator is installed at the output from your transceiver, power amplifier, or antenna tuner in line with the antenna’s feedline
  • When the transceiver is turned OFF, the antenna’s coax signal wire and shield are shorted together and grounded, and both the coax center and coax shield are disconnected from the radio
  • When the transceiver is powered ON, the Actuator re-connects the antenna for normal operating
  • It is intended for HF operation, 160 through 6 meters, and can handle 1.5 kW
  • A good earth ground connection is required for maximum surge protection
  • The Antenna Disconnect is ideal for remote station lightning and static protection
  • The Antenna Disconnect Actuator comes with SO-239 coaxial sockets
  • It is also available with 5-way binding posts for use with twin lead (ladder line) feed lines, such as 450 ohm lines
  • To purchase, please select this option above 12 Volt power for the Actuator comes from the transceiver
  • For modern Yaesu transceivers, simply plug the control cable into the transceiver’s auxiliary power RCA socket
  • For modern Icom transceivers, connect the control wire to the auxiliary socket's pigtails using the crimp barrels
