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 Radio RF Ground Plane Kits
DX Engineering Radio RF Ground Plane Kits provide an effective method of reducing stray RF pickup by equipment and interconnecting cables. Used under and connected to radio equipment, these 1/16 inch thick, pre-drilled aluminum or copper sheets create an RF reference plane that is also connected to the existing grounding bus. As described in the ARRL's "Grounding and Bonding for the Radio Amateur 2nd Edition" by H. Ward Silver, N0AX; a large surface area of metal improves upon the single conductor grounding buss by equalizing the RF E-field (electric field) around equipment and attached cables. This reduces voltage differences between pieces of equipment and the associated currents that cause RF interference to transceivers, microphones and accessories. The reduction in RF interference improves both transmitted and received signal quality. Radio RF Ground Plane Kits are available in 12 versions; three sizes of aluminum or copper plate with hardware and the same three sizes of aluminum or copper plates with companion mounting boards made of 1/2 inch thick Medium Density Fiberboard (MDF), with hardware. All kits are intended for indoor use only. As used by top contesters and DXers alike, a flat metal sheet placed under equipment, along with physically short grounding braids, wires and interconnection cables can significantly reduce the RF voltage differences between cables and equipment. The chance of RF trouble in your equipment is reduced by installing DX Engineering Radio RF Ground Plane Kits in your station.
