DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes
The present-day DX Engineering was launched in the year 2000. To celebrate our 20th Anniversary in the year 2020 we have developed a new line of Baluns and Feedline Chokes. Introducing DX Engineering "Maxi-Core® 20" Baluns and Feedline Chokes. They reduce or eliminate currents on the outside of your feedline allowing you to hear and to be heard much better. They keep more RFI/BCI out of your antenna and receiver and transfer more of your transmitted signal to the antenna for higher efficiency, the best antenna pattern and maximum performance. Signaling a new era of RF performance across the 1.8 to 54 MHz frequency range, DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes handle full-legal-power-plus and provide higher common mode impedance (CMI) across a greater frequency range than competing models and even previous DX Engineering and Comtek models. Years of R&D coupled with major advancements in test equipment and techniques combined with custom ferrite materials have allowed our engineering team to design the DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes. Maxi-Core® 20 Baluns and Chokes have high CMI across the AM Broadcast band and the HF/6M spectrum, which is essential to provide sufficient suppression of unwanted transmitted and received RFI/BCI current on the feedline shield exterior. Hear and be heard with DXE Maxi-Core® 20 Baluns and Feedline Chokes. Choose superior performance from these models: * DXE-MC20-1-1 Maxi-Core® 20 - 1:1 Current Choke Balun - For all HF-6m balanced antennas with a 50 ohm feedpoint, including resonant dipoles, loops, Yagis, beams, etc. * DXE-MC20-FC Maxi-Core® 20 - 1:1 Feedline Choke – This high CMI line isolator is perfect for use in line on 50 ohm coaxial feedlines, at the antenna, tower or shack end of the feedline. * DXE-MC20-1-1T Maxi-Core® 20 - 1:1 Current Choke Balun – This 1:1 "T" model is for force feeding antennas with a tuner. Use it at the end of ladder line of any impedance or mounted on a coax fed non-resonant antenna. This model tolerates operation at high SWR on non-resonant multi-band antennas. * DXE-MC20-C4-1 Maxi-Core® 20 - 4:1 Current Choke Balun is for use on antennas with a 200 ohm feedpoint and at the end of any impedance ladder line, especially on antenna systems with higher impedance. This model tolerates operation at high SWR on non-resonant multi-band antennas. * DXE-MC20-V4-1 Maxi-Core® 20 - 4:1 Voltage Balun is a 200 ohm to 50 ohm transformer for use on random long-wire and OCF antenna applications. This true voltage balun is intentionally designed with low CMI for antennas that need a transformer without RF choking for easier antenna tuner operation and it tolerates elevated SWR. Maxi-Core® 20 Baluns and Feedline Chokes are built into a convenient weather resistant NEMA enclosure that is mounted easily with optional brackets. They feature 1/4-20 stainless steel hardware and a high quality silver-plated PTFE dielectric SO-239 (UHF female) input connector. The SO-239 connector limits power handling to 5 kW at low SWR and reduced power at elevated SWR. These baluns and the feedline choke exhibit very low insertion loss and inherently low SWR. Optional mounting brackets are available for use on wire antennas or for verticals, Yagi and beam antennas. See the Suggested Parts tab after clicking "More Detail" on the model of interest. Combination packages that include balun or choke and mounting bracket are also available.

DX Engineering Receiver Guard Electronic RF Limiters
DX Engineering Receiver Guard RG5000HD Electronic RF Limiters are the best choice of inline devices to protect your receiver antenna inputs. The Receiver Guard is a receive antenna input limiter specifically designed to protect a sensitive receiver front-end against high levels of RF and potential damage. At the heart of each Receiver Guard is a highly effective electronic RF limiter covering 500 kHz to 150 MHz with an insertion loss under 0.15 dB up to 50 MHz and under 0.30 dB up to 150 MHz. The multi-stage design includes a gas discharge tube for maximum pulse energy protection. The DXE-RG5000HD rejects 10 watts of catastrophic receive antenna feedline RF while passing a maximum signal of about 87 dB over S-9, which is only 25 mw, a signal level that is well below the point of front end damage. Receiver Guards are a must for multiple radio contesting stations and they provide low-cost front-end "insurance." Use them in these common high-RF situations: - Receive antennas in very close proximity to transmit antennas - Field-day operations with many transmitters in close range - Multi-transmitter contesting sites - Neighboring Amateur and CB operators - Frequent high-power mobile encounters Extensively tested and proven in real-world stations, the Receiver Guard works for all radios and offers the ultimate performance required by the upper tier of transceivers tested to have the best narrow-spaced third-order dynamic range or published RMDR (Reciprocal Mixing Dynamic Range). These are passive electronic limiters, so competitive contesting stations use separate band filters in addition to the Receiver Guard. When there are high levels of RF on your receive antennas, the DX Engineering Receiver Guard generates far less harmonic noise than other limiters on the market, which allows your station to continue to operate safely and competitively. At normal HF signal levels the RG5000HD operates continuously with no effect on the performance of your station while providing the best possible protection for your radio. Here are key Receiver Guard features: * Keeps stray high levels of RF from damaging your receiver input * Ideal for separate 160 and/or 80 meter receive systems with large pulse and RF energy capture area * Uses state of the art components for maximum protection of receivers * Under 6 ns response time * Multi-Stage protection * Very low insertion loss * Uses BNC type connectors to avoid accidental connection to a transmit feedline * Has been developed and tested in world-recognized multi-multi contest station K3LR Specifications - DX Engineering Receiver Guard model DXE-RG-5000HD - Frequency Range: 0.5 through 150 MHz - Insertion Loss: < 0.15 dB up to 50 MHz, < 0.3 dB 50 MHz up to 150 MHz - VSWR: < 1.2:1 - Maximum Output Level at 10 W input: +14 dBm (0.025 W) - Maximum Power Handling: 10 W CCS (Continuous Commercial Service) - Device Impedance: 50 to 75 ohms, unbalanced - Connectors, Input and Output: BNC female Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.

Better receiving performance than full-size transmit antennas and other active makes the DXE-RSEAV-1 the best choice on the market for VLF through HF reception, including long-distance AM broadcast, Medium Wave and Shortwave (SWL), and new low-frequency Amateur bands, DXing, contesting, and everyday HF operations. Click on a listed product title and Scroll Down to see additional important information. A complete product description appears below the Specifications Overview. Instruction manual links appear in the Documentation section. The sleek and stealthy DXE-RSEAV-1 includes a high-quality three-section 8.5 ft. (2.6m) aluminum tubing whip, insulated mounting plate and the completely new DXE-AVA-3 Active Matching Unit. Its state-of-the-art broadband operational amplifier design works as a high-impedance buffer between the short antenna element and RG6U 75-ohm coax. When installed in the appropriate location, RSEAV antennas provide significantly better weak signal reception than other active receive antennas and full-size transmit-capable antennas, with substantially reduced noise and lower spurious signal interference. Receive Short Element Active Vertical Antennas are intended to be mounted on a ground rod at ground level in a clear area away from all metal, towers and other antennas. They are sold individually (DXE-RSEAV-1), or with a bias tee (DXE-RSEAV-1FVI) and DXE-RSEAV-1 Receive Short Element Active Verticals set a new standard for "Active Receive Vertical Antennas" replacing legacy DXE-ARAV-3, ARAV-2, ARAV-1 and AL-24 versions. Use multiple DXE-RSEAV-1 for all 4 and 8 element DX Engineering Receive Arrays – all 3, 4 and 8 element Hi-Z Antennas Arrays – and 2 element receive arrays with DXE-NCC-2 and NCC-1 Variable Phasing Controllers. The DXE-RSEAV-1 is designed to be a very low-gain, low-noise antenna for greatly improved signal-to-noise performance over a very wide range of frequencies. In a proper single or multi-element array installation, this Receive Vertical antenna will attenuate high-angle skywave signals, which is the goal for a low band DXing receive antenna. Low-angle, long-range DX signals are easier to copy with a good radio and DX Engineering Receive Short Element Active Vertical Antennas. Please Note: To achieve the expected reception pattern, multi-element phased arrays depend upon identical gain and phase response from each element. Every individual element amplifier, its grounding, and even its feedline characteristics and length, must be identical to the others in the array. Therefore, when unrepairable failures occur, it is essential to replace or upgrade all the elements in the array with identical, fully compatible DXE-RSEAV-1 antennas or DXE-AVA-3 units.

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.

DX Engineering KD9SV Keying Relay, DXE-SV-KR, is a high speed Solid State interface designed to protect transceiver keying circuits from potential damage by amplifier relays. Transceiver low voltage keying circuits handle only a few milliamperes (mA), but some "modern" amplifier relays require over 150 mA at 12 VDC. High voltage and high current amplifier keying relays were common in amplifiers made between 1950 and 1975. The DXE-SV-KR can safely key almost all DC amplifier relays, including older relays and keying inputs that operate at high voltage, typically -100 VDC or +110 VDC. Inspired by the original KD9SV Keying Relay, the DXE-SV-KR quickly and silently does the work of a 6-pin normally open (N.O.) Double Pole Single Throw (DPST) relay. It provides two completely isolated ground independent PTT Outputs, each capable of handling up to +/- 450VDC at up to 500mA. The DXE-SV-KR optically isolated PTT Input only requires 2mA at 13.8VDC to key, so it is safe for any transceiver's amplifier keying circuit or any other 'ground-on- transmit' PTT keying accessory. Built in a convenient enclosure with RCA phono jacks, the DXE-SV-KR is also QSK capable for keying any amplifier that supports high speed CW keying, typically a Solid State amplifier (or specially equipped tube amplifier) with a high-speed circuit for "Key In" PTT. The DXE-SV-KR may also be used to isolate a straight key or a Solid State electronic keyer connection to any CW key input. It can provide crucial protection and safety on high voltage CW key jacks and circuits common on old tube-type transmitters and transceivers. The DXE-SV-KR Keying Relay's high speed capability also provides relay debouncing, or it can be used as a remote high-voltage DC switch. The DXE-SV-KR operates on 13.8VDC to an input 2.1mm DC connector. A mating 2.1mm plug and wire are included. The DXE-SV-KR features standard RCA phono female connectors for ground-on-transmit Input and Output ports and is compatible with almost every transceiver or transmitter and amplifier combination. RCA phono patch cables are sold separately. The DX Engineering KD9SV Keying Relay is an uncomplicated way to ensure that your sensitive transceiver or electronic keying circuit is isolated and protected. CAUTION: DO NOT connect the DXE-SV-KR to AC voltage relays in antique amplifiers, typically 110VAC. See instructions. Except for AC switching, the DXE-SV-KR replaces the Ameritron ARB-704.

DX Engineering® OMNI-TILT® Vertical Antenna Tilt Bases
DX Engineering® OMNI-TILT® Vertical Antenna Tilt Bases are a completely new design that incorporates features that make this Tilt Base a 'must-have' for all types of vertical antennas. The OMNI-TILT® is patterned on the same proven safe technology as the patented DX Engineering® SAF-T-TILT® and the patented DXE-TB-3P Tilt Bases, that are designed to prevent the antenna from falling when the fasteners are loosened. The user simply lifts the OMNI-TILT® base plate and this positive action disengages the bolts from the top slot, which allows the user to easily and safely walk the ground-mounted antenna up or down for tuning, maintenance, stealth antenna stowing, or in the event extreme weather is on the way. Order one of these OMNI-TILT® models for your vertical antenna system: DXE-OMNITILT-1P for Hustler BTV Series and Hy-Gain AVQ Series Trap Vertical Antennas--Both antenna types use the supplied DXE-TVA-HWK Trap Vertical Mounting Hardware kit. DXE-OMNITILT-2P for Elevated Mount Verticals, include Cushcraft R8, R9, Hy-Gain AV-640, MFJ, GAP and many other antennas for HF and VHF – DXE-OTMC-250P Clamps (2) are included for customer-supplied upper antenna support tubing or pipe of 1.25 to 2.50 in. OD. NOTE: Both models REQUIRE two (2) optional DXE-OTMC-250P clamps to attach the non-tilt part of OMNI-TILT® to a user-supplied lower Mast Pipe of 1 1/4 to 2 1/2 in. O.D. The ability to attach this tilt base and your antenna to a pipe from 1 1/4 up to 2 1/2 in. is an important new feature of the OMNI-TILT®. Alternatively, all OMNI-TILT® models may be mounted on a 4 x 4 in. or larger wooden post with user-supplied attachment hardware; typically lag screws. This is why the DXE-OTMC-250P clamps for the non-tilt portion are NOT SUPPLIED, as they would be unused with wood-post installation and at added expense. DX Engineering® OMNI-TILT® bases are custom made from laser cut 1/8 in. thick Stainless Steel for strength and durability. All of the hardware used in the OMNI-TILT® Base is Stainless Steel to ensure long and dependable service. The DX Engineering® OMNI-TILT® is a 2-piece assembly of stainless steel U-shaped plates. As noted above, the OMNI-TILT® rear plate is typically mounted to your 1.25 in. to 2.50 in. steel pipe using the optional DXE-OTMC-250P Mounting Clamps, purchased separately for either model. The OMNI-TILT® front plate pivots on a pair of high-strength bolts.

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.
