DX Engineering Control Line Terminal Boards
DX Engineering Control Line Terminal Boards are designed to provide a flexible and simplified approach to control line surge protection. The DXE-CLTB is a small, 3 inch square printed circuit board (PCB) with four ten-wire compression screw terminal blocks that handle from 14 to 26 AWG conductors and up to 10A. The two outer terminal blocks are for input and output of the control wires and the two 45 degree angled ten-wire compression screw terminal blocks are for connecting the required number of individual electronic surge protection components. This provides for the choice of components to install between the control line and ground for shunt protection. Metal Oxide Varistor (MOV), Gas Discharge Tube (GDT), EMP Suppressor TVS Diodes, RF Bypass Capacitors and other wire lead components are easily connected between each control line conductor and ground with the DXE-CLTB. This open-board, no-chassis concept allows easy mounting on a single point grounding panel, to support simplified inspection and exchange of control line electronic surge protection components that should be done on a regular basis. For effective protection wherever electronic devices are used as a shunt to ground, a low impedance ground is crucial. The DXE-CLTB Control Line Terminal Board has four corner ground plane screw holes. It includes a hardware kit of four self-tapping screws, spacers and external tooth washers, for mounting the PCB on a metal grounding panel inside an enclosure. The DXE-CLTB-M Control Line Terminal Board also includes a 10-pack of MOVs. The following components are available separately for a variety protection projects: DXE-MOV-82VDC-10 Metal Oxide Varistor, Surge Protector, max. 82VDC/50VAC Pack of 10 DXE-GDT-4KV-5 Gas Discharge Tube, Surge Arrestor, 4kV, Pack of 5 DXE-TVS-1500-10 ESD Suppressor, TVS Diode, Bidirectional, 17VDC max., Pack of 10 DXE-CAP-PT1UF-10 Capacitor, Ceramic, 0.1uf, 1kV DC, RF Bypass, Pack of 10

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.

DX Engineering Ladder Line Surge Protector
Built by popular demand, the DX Engineering Ladder Line Surge Protector is ready to be placed in line with your balanced feedline antenna system! For many years, hams have asked us for a surge protector for use with their 300 ohm and 450 ohm ladder line fed antennas. Decades ago automotive spark plugs or arc gaps were used for shunting lightning pulses from balanced feeders to ground. But, you never really knew if they were going to work, if they really were continuing to work or if they were affecting the tuning. Here is the modern approach to providing surge protection for ladder line fed antennas. Made with components similar to those used in coaxial protectors, the DXE-LLSP uses much larger capacitors, resistors and gas discharge tubes on each leg of the ladder line to offer excellent surge protection capabilities at high SWR. These components are rated to handle 5 kW, so this protector will easily handle well over legal limit RF power at the high standing wave ratios expected on balanced line. Plus, the Ladder Line Surge Protector bleeds off the static charge that is collected on your antenna from wind driven sand, rain and snow! The DXE-LLSP Ladder Line Surge Protector is built to sustain multiple minor surges. As with any surge protector, there is no guarantee that a direct hit from lightning will be stopped. A replacement parts kit is also available to refurbish your pulse damaged protector: DXE-LLSP-RP Features of the DX Engineering Ladder Line Surge Protector: • Standard size NEMA enclosure; 4 x 4 x 2 in. nominal box dimensions; mounting tab holes on centers: 4.625 x 2.125 in. • Works with 450 ohm or 300 ohm Ladder Line and 600 ohm open-wire feeder • Internal Gas Discharge Tubes, Capacitors and Resistors • Can withstand multiple minor surges and shunts them to ground • Bleeds off static charge collected from wind driven snow, rain and sand • Weep holes allow any buildup of internal moisture to drain out • Handles well over legal limit at high SWR as expected on balanced line NOTE: The DXE-LLSP is an RF only device that does not carry DC voltage. Therefore it cannot be tested with a multimeter. It must be tested with an analyzer and a 300 ohm resistor, or by connecting an antenna feedline. If there is infinite SWR or no receive, the components have been damaged by lightning pulse energy and need to be replaced with the DXE-LLSP-RP Ladder Line Surge Protector Replacement Parts Kit. Order the DX Engineering Ladder Line Surge Protector for your balanced feedline antenna system today!
