DX Engineering Rotator Control Line Protectors
DX Engineering Rotator Control Line Protectors are custom made surge protectors designed for use on rotator cables - up to 8 conductors. We routinely protect power and antenna cables, why ignore rotator control cables? These protectors are also ideal for control lines of remote antenna switches and any low voltage control system where voltages are normally below 60V DC or AC. External terminals allow convenient connection while the surge devices remain securely protected inside the metal enclosure. DXE-IS-RCT features include: * Weatherproof metal enclosure with cover, mounting stud and terminal gaskets to deter water from entering the enclosure. * Terminal strips to connect up to eight rotator control wires * 1/4 in. x 20 mounting stud allowing multiple mounting configurations * Each line connection has an individual shunt MOV for maximum surge protection * Voltage spikes exceeding 82 Vdc (in either polarity) will be shunted to ground * RoHS compliant construction DXE-IS-RCT protectors are recommended to be installed on a tower leg or ground rod using an optional DXE-J-1 or DXE-J-2 Grounding Clamp or a DXE-UCGC Copper Ground Rod Clamp. The location you choose for your DXE-IS-RCT should provide a good, low-impedance ground connection. The surface to which a grounding clamp is connected should be thoroughly cleaned to a bright-colored surface and then treated with a conductive anti-oxidant coating. This procedure will minimize weather-related complications and improve conductivity for your DXE-IS-RCT. DXE-CCK Copper Cleaning Kits provide cleaning pads and copper paste which is ideal for this application. If a tower or mast is being used and is properly grounded, your DXE-IS-RCT may be connected to the base of that structure just above the grounding point. For best results, follow the installation instructions carefully. As with all electronic equipment, observe proper safety considerations. For example: Do not install your DXE-IS-RCT if there is a storm anywhere in your area. Do not adjust or touch the grounding system equipment when there is a storm anywhere in your area. Make sure all power is removed before making any adjustments or working on any ground system or grounding components. DXE-IS-RCT Specs: Surge Energy: 6500 A or 38 J (Max energy 8/20) Response Time: 10 ns typical, 25 ns max. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. For the best protection of your rotator systems, order and install your DX Engineering Rotator Control Line Protectors and keep the voltage surges off of your control lines.

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.

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.

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.
