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. Paradan Radio Dual Antenna Disconnector Specifications: * Power Handling: Over 1.5 kW on each circuit * Insertion Loss: Less than 0.05 dB below 29 MHz; 0.4 dB at 54 MHz; 1 dB at 144 MHz * Relay Operating Voltage: 10-18 V dc * Current: 120 mA at 13.8 V, when turned ON to connect antennas * LED: Illuminates green when relays connect the antennas for operating * Relays: Four relays with 15 amp contacts each, protected for reverse spikes * Case: Grounded to Antenna connectors and isolated from Radio coaxial connectors * Control Wire: 6 ft., two-conductor AWG 18 with RCA phono plug * Control Input: Diode protected against reverse polarity; RF filtered * Active Lightning Protection: Gas Discharge Tube on both Antenna inputs * Case Ground Stud: 1/4 in. (1/4-20) with washers, lock washer and nut * Case: Diecast aluminum, black paint, white print, water resistant * Size: 6 in. x 3.8 in. x 2.2 in., mounting tabs with 4 holes spaced at 5.25 in. and 2.50 in. on-center * Weight: 1 lb. 10 oz. ® Registered trademark of Anderson Power Products

Paradan Radio Antenna Disconnect Actuators
Paradan Radio Antenna Disconnect Actuators are installed in the coaxial cable that feeds the antenna. When power from your transceiver or station power supply is turned off, they automatically disconnect the antenna from your station and ground the antenna feedline. This reduces the chance of station damage from lightning while you're away. The ADA also has a gas discharge tube to protect the radio from lightning pulse damage while operating. Eliminating the wear and tear on transceiver and station connectors from repeated physical disconnection and reconnection, the Paradan Antenna Disconnection Actuator takes care of grounding antenna feedline automatically. It safely prevents static-discharge, surges, and lightning pulse effects from damaging your radio and associated equipment without having to remember to unplug the system and wear out the connectors. This is especially helpful for stations that are located on upper floors of the home where grounding is an issue. The water-resistant enclosure of the ADA may be installed in the shack at the output of the transceiver, amplifier or tuner—or outdoors in line with the antenna coaxial cable. Connect the DC cable into +12 Vdc source, either from the transceiver or power supply that is turned off when not operating. When power is on, the ADA is powered, and the antenna feedline is automatically connected. When DC is off, the antenna's coax center and shield are shorted together and grounded. The case is grounded to the antenna's coax connector but is isolated from the radio's coaxial connector. The Paradan Antenna Disconnect Actuator LED illuminates green when its two 15 ampere contacts RF relays connect the antenna. The relays have diode protected coils to eliminate reverse spikes, and they handle 1,500 watts of RF from 1.8 to 50 MHz; they also have two SO-239 (UHF female) connectors. Specifications for the Paradan Radio Antenna Disconnect Actuator, PDN-P-ADA-1: * Operating Power: 10-18 Vdc at 60 mA when turned ON to connect antenna * Insertion Loss: <0.05 dB at 30 MHz, <0.1 dB at 54 MHz * Power Handling: 1.5 kW * Control Wire: Two-conductor 18 AWG with RCA phono plug RED to center pin, BLACK to plug shell, may be lengthened or re-terminated as needed * Control Input: Diode protected against reverse polarity; RF filtered * Active Lightning Protection: Gas Discharge Tube on antenna coax input * Case Ground: 0.25 in. stud with washers, lock washer and nut * Case: Diecast aluminum, black powdercoat, white print, water-resistant * Size: 4.8 x 2.6 x 1.6 in., mounting flanges with four-hole on-center spacing of 5.25 in. by 1.50 in. * Weight: 0.81 lbs. (360g)

Paradan Radio Antenna Disconnect Actuators for Ladder Lines
Paradan Radio Antenna Disconnect Actuators for Ladder Lines reduce the chance of station damage from lightning surges. The Antenna Disconnect Actuator automatically disconnects the antenna from your tuner and radio and grounds the antenna. It helps prevent static discharge, surges, and the effect of nearby lightning strike pulse events from damaging your tuner, radio and associated equipment. This Antenna Disconnect Actuator is excellent for protecting remote stations from lightning surge. This Antenna Disconnect Actuator operates on 10 to 18 Vdc, which may be supplied by a transceiver equipped with a DC output. Or, connect it to your power supply that you turn off when not operating. When the power is turned OFF, the antenna's two binding posts are shorted together and grounded, and shack side binding posts are disconnected. When powered ON, the Actuator reconnects the antenna for normal operating. Just insert each wire from the twin lead ladder-line into the binding post hole and secure by tightening the red and black post nuts. It comes with a Ring Terminal, four Barrel Connectors, and a Powerpole® connector pair.
