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 Guy Line Guards
DX Engineering Guy Line Guards are used on towers to prevent damage to coaxial cable rotator loops from rubbing directly on metal guy lines or dead ends. Guy Line Guards are a high visibility yellow poly plastic tubing material that is split lengthwise for easy installation on existing guys. Each Guard features a single hole for the included zip-tie to secure it in place. For coax protection they are mounted at the top of the guy lines and, since they are yellow in color, Guy Line Guards may also be mounted at the bottom of the guy lines to warn people that the guy line is present. Guy Line Guards are approximately 45 inches (1.14 m) in length and come in a set of three.

DX Engineering Phillystran Steel Tail Kits
DX Engineering Phillystran Steel Tail Kits provide the appropriate transition from non-metallic to metallic guying cable at the ground end of tower guying systems. Steel Tail Kits are available for Phillystran HPTG-4000I, -6700I and 11200I Guy Lines. What is the function of the steel tail? Here is the recommendation by Phillystran, the manufacturer of HPTG-I High Performance Tower Guy non-metallic guy lines: A steel tail is a length of EHS (Extra High Strength) steel guy line connecting the HPTG-I assemblies to the turnbuckle or guy anchor. The steel tail protects the HPTG-I assemblies from damage due to brush fires, lawn maintenance equipment or vandals. The steel tail length should be sufficient to get the bottom end of the HPTG-I assembly above arm's reach, or above brush tops (if located in a marsh or tall brush area). The HPTG-I should never pass through tree limbs or be allowed to rub against poles or trees. The steel tail allows for easier guy length calculations and serves as a guy tension monitoring point, as well as a safer area to attach guy grips during guy line installation and tensioning. Eliminating the hassle of buying a length of steel cable and obtaining a special tool to cut it, DX Engineering Phillystran Steel Tail Kits provide everything needed to isolate your tower's non-metallic guy cable from harm. Three different size kits are available for different tower guying requirements provided by Phillystran guy cables 4000I, 6700I and 11200I. Here are the items included in these innovative Steel Tail kits: - 12 ft. EHS steel guy line, Galvanized, in three kit sizes, 3/16 in., 1/4 in. or 5/16 in. - Porcelain Guy Line Strain Insulator, 502 or 504 depending upon kit size - Galvanized Steel Preform Dead End Big-Grips for EHS steel guy line, two per line - Heavy Duty Thimble, galvanized steel, appropriately sized for each kit - Cable Ties, UV protected Black, four, to secure installed Big-Grip ends Note: Phillystran guy line and Preform Dead End Big-Grips for Phillystran are not provided in this kit and must be ordered separately. DX Engineering Phillystran Steel Tail Kits provide Porcelain Guy Line Strain Insulators for the top end of the Steel Tail so that the galvanized steel Big-Grips for the Phillystran and for the EHS Steel Guy Lines do not touching and make RF noise. For three different size Phillystran guy line, HPTG-4000I, -6700I and -11200I, these kits are available exclusively from DX Engineering in 3-packs for each level of tower guying.

DX Engineering Bent Pin Shackles
DX Engineering Bent Pin Shackles are used for guy line attachment to towers for Amateur Radio and commercial applications. Also known as a clevis in the power industry, these shackles are specially designed with a removable bent bolt and locking nut to go through the outer hole of the matching guy strain insulators commonly known as the "502" or the "504" in ham radio tower work. Forged from 1/2 in. steel and hot dip galvanized, these Bent Pin Shackles have a minimum ultimate strength of over 12,000 lbs. and have a rounded end large enough to be used around a tower leg. However, they are typically connected to a guy attachment tower ear or guy bracket, with a screw pin shackle used as a link. The insulators that fit inside of this shackle accept the guy line big grips from either metal or non-metallic guy lines. For those who already have insulators, Bent Pin Shackles are offered in a set of three for each level of guying. We sell the matching DXE-502 and DXE-504 insulators in sets of three. Also available are two kits that include three Insulators of either size and three Bent Pin Shackles. Look to DX Engineering for the unique tower hardware that you need.

DX Engineering 450 Ohm Ladder Line
DX Engineering 450 Ohm Ladder Line is a transmitting grade low-loss parallel-wire RF feedline featuring a strong, waterproof, UV black polyethylene insulation. To maintain the wire spacing between the conductors while reducing losses, the integral flat plastic material alternates with rectangular openings, which explains the "Window Line" nickname. Capable of handling over 3 kW of RF power, DXE-LL450 is a very low-loss transmission line across HF. It is ideal for exceptionally long feedline runs and for low band wire antennas operated on multiple bands on which the feedpoint impedance can vary significantly, causing mismatch and elevated SWR. Unlike coaxial cables, DX Engineering DXE-LL450 Ladder Line maintains low RF losses at frequencies where antenna feedpoint impedance mismatches cause high SWR. It can provide significantly higher efficiency than coaxial cable when feeding non-resonant antenna systems that are matched with a wide impedance range antenna tuner. DXE-LL450 450 Ohm Ladder Line is a high-quality flat RF feedline, about 0.938 in. wide (15/16") with two 16-gauge copper-clad steel wire conductors (29 AWG x 19 strands) that provide the strength to hold up for long spans between supports without twisting. It exhibits a nominal impedance of around 400 Ohms and a nominal Velocity Factor of 91 percent. For proper performance, LL450 Ladder Line must be installed suspended through the air supported by insulators every 25 ft. or less, kept at right angles and several inches away from other wires, and at least one foot away when run parallel to the earth or large metal surfaces. Installing with an axial twist of one turn per 10 ft. can reduce wind, rain and ice loading, RF coupling and RF noise. DXE-LL450 can be mounted with insulators and suspended on metal or wood posts or run along a wood fence line, only if the fence has no wires or metal mesh that couples RF noise or unbalances the feedline. Often used for non-resonant wire doublet antennas, DXE-LL450 can be more easily terminated outdoors to a DXE-MC20-C4-1 4:1 Balun or a DXE-MC20-1-1T 1:1 Balun. Then, with no inline switches or relays, directly connect the antenna system to a typical indoor wide range antenna tuner using a solid dielectric coax, not foam dielectric, to handle high voltage at high SWR. DXE-213U or DXE-214 Coaxial Cable Assemblies 12 or 18 ft. with PL-259s are perfect for this method, which eliminates the need for a special balanced tuner, and avoids the losses and detuning effects caused by unbalancing when ladder line is routed indoors near wires and ducts. DXE-LL450 is sold by the foot, previously sold as DXE-LL450-CTL, this is the same ladder line with a new part number. It is also available in spools of 500 ft. DXE-LL450-5C and 1,000 ft. DXE-LL450-1K, which are specified for DX Engineering Reversible Beverage System Antennas. NOTE: This type of feedline is intended for MF and HF use and is not suitable for use above 54 MHz. Also consider DX Engineering 300 Ohm Ladder Line, DXE-LL300, an excellent alternative low-loss HF feed line that reduces impedance extremes on non-resonant HF multiband antenna systems.

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 RF Attenuators
DX Engineering RF Attenuators are used inline with receiving equipment for testing purposes. An inline attenuator will limit the RF input to preamplifier to prevent overload or be used to pad the output of a high gain preamp to an appropriate level. Adding an inline attenuator to a receiver input allows determination of accuracy of s-meter readings on transceivers with a constant RF input signal source. Sometimes, the level of low power RF equipment needs to be reduced for measurement or to obtain the proper input level to an amplification device, such as with QRP equipment. Specifications of impedance, attenuation, power handling and connectors appear on the part number description. Order inline RF Attenuators for your test bench or shack from DX Engineering.

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.

DX Engineering Key Line Combiner
DX Engineering Key Line Combiner – DXE-3RIGKEYLINE is another handy gadget that can take the ground-on-transmit amplifier keying lines from up to three transceivers or other devices and connect them to one amplifier or accessory. All four connectors are female RCA phono. After we came out with the DXE-KEYLINE-3 for one radio to key an amp and two other accessories, then the requests for this DXE-3RIGKEYLINE combiner came in. It really isn't surprising that many hams have multiple transceivers but only one amplifier. So, while a coax switch handles the RF, now the DXE-3RIG-KEYLINE handles the PTT keying from three radios to one amplifier. We also have a two-input, two-output combiner-splitter DXE-KEYLINE-DUAL, if that fills your needs. Each keying input of this device is guarded with a separate 45V 2A Schottky diode, providing ground-on-transmit isolation between each rig keying line. Therefore, this combiner will keep the load or voltage of any one device from affecting the others. This device is passive, meaning that it requires no power to function. It is not a transistor buffer and it has no relays. The DX Engineering Transceiver Key Line Combiner DXE-3RIGKEYLINE allows two or three ground-on-transmit keying lines inputs to key this unit's single output. It's another handy device that can be used in lots of ham shacks and it's a great gift item for the Amateur Radio operator who has everything… except one of these gems!

This single-input, triple-output passive DC only unit provides multiple PTT keying lines, two for other accessories in addition to one for the amplifier. All four connectors are female RCA phono. Many special Amateur Radio devices, from receive accessories to simple phasing units and even automatic antenna switches, need to use the same T/R keying line as your amplifier. But they don't have a keying line pass-through for the amplifier. The Transceiver Key Line Splitter is that handy item that is needed in almost every shack! It's a great gift item for the ham who has everything! Developed by Ed, K8IV, you can think of it as an "IV" line for your radio's amp keying output, allowing more than just an amplifier to switch when your transceiver goes to transmit. Each keying output of this device is guarded with a separate 45V 2A Schottky diode, providing ground-on-transmit isolation between each accessory keying line. Therefore, this splitter will keep the load or voltage of any one device from affecting the others. But, the KEYLINE-3 input depends upon the voltage and current rating of your transceiver's transistor or relay keying circuit for an amplifier, so check your manual for the total that it will safely handle. Most accessory keying lines send 13.8 Vdc at only a few milliamps, so this combination typically works without issue. The KEYLINE-3 is passive, meaning that it requires no power to function. It is not a transistor buffer and it has no relays. We really want to call it the "Key Line 3.14" - (key line pi). You know… three outputs from one input with a total of four phono female connectors. But we can't call it a "pie" because someone might think they are buying some kind of non-raspberry micro-PC or something! No, it's just a splitter.

When inserted into the line in either direction, they block DC current from passing through while permitting RF signals to flow. These units effectively block DC current from entering where it's not wanted—on antenna lines where DC powers other devices. The blocks will keep DC out of your receiver input! Their straight, inline form factor is perfect for most applications. Use these DC blocks at frequencies from 5 to 2,500 MHz! For example, they're ideal for isolating amplified Sirius/XM antenna voltage from your receiver. They easily handle up to 24 Vdc. Block that DC!

DX Engineering NPA RF Attenuators
DX Engineering NPA RF Attenuators reduce the amount of signal carried within coaxial cables. This signal attenuation is sometimes needed to ensure proper receiver operation. When amplified antennas and inline amplifiers are used with short cable runs, it's possible to have too much signal arriving at the radio. Excessive signal may over-drive the receiver and create distortion or self-generated interference. When this happens, knocking the signal down a bit is the best remedy. DX Engineering RF Attenuators are Non-Passing Attenuators (DC blocking) in 10 or 20 dB attenuation levels. They may be combined for attenuation levels beyond 20 dB; however, this is very rarely needed. Operation is from 500 kHz to 2.4 GHz. When you suspect that you have too much signal reaching your radio, grab one of these DX Engineering NPA RF Attenuators!

DX Engineering RTR-2 Modular Receive-Transmit Interfaces
DX Engineering RTR-2 Modular Receive-Transmit Interfaces provide the easiest and safest method for connecting a dedicated receive antenna to an HF transceiver that does not have a separate receive antenna input. Placed inline with the transceiver's antenna connector, the RTR-2 does the job of a 200 watt T/R relay using the amplifier keying line for failsafe protection, so your transmitted energy cannot go to the receive antenna. Three internal Plug-in Module option slots provide added features and protection: * DXE-RPA-2-PM Receive Preamplifier Plug-in Module * DXE-TRI-PM Transmit Receive Interrupter Plug-In Module * DXE-IT-PM 75 to 50 ohm Impedance Transformer Plug-in Module DX Engineering RTR-2 Modular Receive-Transmit Interfaces allow the standard transceiver owner to enjoy the advantages of separate receive antennas. For the unswitched receive antenna (RX ANT) port on expensive transceivers, the RTR-2 interface also adds inexpensive failsafe protection. The receive antenna line can be opened or grounded with the optional DXE-TRI-PM Interrupter plug-in module. The RTR-2 is a very useful device for many applications, including: * Connection of external receiving antennas to transceivers lacking external antenna ports * T-R antenna switch for older equipment using separate transmitters and receivers * Interfacing antennas to older phasing or noise cancelling systems * Addition of a switchable receive preamplifier to any transceiver or transmitter and receiver combination * Excellent failsafe receiver protection for close-spaced transmit and receive antennas, without performance degradation of diode circuits of other devices. RTR-2 units feature a unique, failsafe connection method that prevents the hot switching and timing errors that are common on other transmit/receive relays. RTR-2 interfaces switch fast enough for partial break-in CW operation. There are many simple applications for the new RTR-2 and now internal modules can add dramatically improved reception of those really weak signals on the crowded HF bands! DX Engineering RTR-2 Modular Receive-Transmit Interfaces enable operators to enjoy improved reception with any low noise receiving antenna system. This shielded enclosure relay system provides a safe method of connecting a receive antenna, such as a Beverage, Active Receive system, or other receiving accessories to your radio. Major features that make the DX Engineering RTR-2 Receive Antenna Interfaces your best choice for a receive T/R system device: * New Status Indicating Color-changing LEDs * Three internal slots for new DX Engineering modules * New Key Line Out connector for Amplifier * New internal jumper for placing DC on the Receive Antenna feedline for Active or Loop receive antennas * Attractive and heavy stainless steel enclosure * 200 watts RF switching capability * Supports CW partial break-in * Main transmit antenna connector is SO-239 (UHF female) * Radio RF connector is SO-239 (UHF female) * Receive antenna input is 75 ohm F connector * Receive outputs are standard 75 ohm Type F connectors * Inputs are 50 ohm BNC or 75 ohm F (Optional transformer module available) * Safe switching--transmit antenna is always connected to transceiver on power-off * Hot switching lockout--disables receive antenna during transmit mode (Optional DXE-TRI-PM can be set to short the RX ANT line) * Versatile--allows inclusion of Optional RF preamplifiers and other plug-in modules * Simple 13.8 Vdc input for all operations An indispensable accessory for the DX enthusiast and useful for any Amateur's shack, DX Engineering RTR-2 Modular Receive-Transmit Interfaces can help you expand and improve your station's antenna connections and the protection of your equipment.

DX Engineering Grounding Clamps
DX Engineering Grounding Clamps are used to connect wire grounding conductors of AWG 2 through 10 to a ground rod, tower leg or grounded pipe. These clamps are manufactured from cast bronze, a highly conductive copper alloy, and include high quality 1/4-20 stainless steel screws for maximum longevity and durability. These clamps also accept the stud from our IS-RCT control line protectors, to provide the proper protection of rotator control lines at the base of a grounded tower. Please note that pipe is measured by ID, not OD. For example, 1-1/4 pipe is much larger than 1-1/3 in. OD. DX Engineering Grounding Clamps are available in two sizes, to fit your grounding project. These are great general purpose grounding clamps to have on hand for future projects, so add a few to your order today!
