PolyPhaser Coaxial Lightning Protectors
PolyPhaser Coaxial Lightning Protectors are designed for general, single-transmitter use in the 1.5 to 700 MHz frequency range. PolyPhaser protectors are available in two mounting styles: "Bulkhead Mount" protectors have a longer connector and hardware to mount it through the grounding panel. "Flange Mount" protectors anchor to a grounding panel with both connectors parallel to a flat surface. PolyPhaser Coaxial Lightning Protectors use a DC blocked specially configured gas tube design that has no DC continuity between the two center pins. PolyPhaser's multi-strike products are designed to pass RF frequencies and block all DC. These protectors appear as a DC open between surge and protected ports and offer industry-standard protection. PolyPhaser protectors are suitable for all types of antennas, even "floating" antennas that are not DC grounded. With PolyPhaser DC Blocked protectors, any slow voltage build up from wind driven rain, snow or dust, will not get to the equipment. As the protector reaches threshold for turn-on in a dc blocked circuit, it will go into a momentary soft turn-on as the gas barely ionizes and bleeds the static charge to ground. This does not create noise since it will not get to the arc mode and lasts only a short time. PolyPhaser protection devices have been chosen and specified by communications systems engineers and technicians for 24/7 service in broadcasting, commercial, military and government installations. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Trusted by Amateur Radio operators for over 40 years, PolyPhaser Coaxial Lightning Protectors are ready for your antenna system installations. They are available here, at DX Engineering.

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.

Par EndFedz® Antennas
Par EndFedz® Antennas are End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth portable operations. These single-band and multi-band antennas can be mounted horizontally, vertically, or as a sloper. No ground plane or counterpoise is needed so portable operation could not be easier. Simply hang the far end from a tree limb or send the wire out a hotel room window or balcony. You can use a telescoping fiberglass mast to get the antenna really high in the air and the supplied end insulators the installation easy. Stealth operation in CC&R and HOA antenna restricted locations is simplified. Their all-black construction makes them difficult to see. Each Par EndFedz® features a UV-resistant black ABS plastic housing with a support rope attachment hole that encloses a matching network to allow the antenna to be fed with standard 50 ohm coaxial cable with a PL-259 (UHF male). All hardware is stainless steel and the SO-239 (UHF female) connector is silver plated and has a PTFE dielectric. The antenna wires are either 18 or 26 AWG stranded Copperweld® with 200 pound breaking strength and a tough, 100% UV stable black polyethylene jacket. One end of the antenna wire has a #10 solder lug making attachment to the matching network feedpoint simple and easily replaceable, if necessary. Standard single and multi-band versions handle 100 or 200 watts and higher power versions handle 300 watts. Lightweight QRP PolyStealth models handle 25 watts and are ideal for portable operation because they are lightweight; the MKII model weighs only 8 ounces and the Trail Friendly model weighs only 3.5 oz. Par EndFedz® Antennas require no counterpoise or extra conductors. The EF-ALLBAND-KW model, about 133 ft. in length, covers eight bands, 80 through 10 meters. The ALLBANDKWJR is 74 ft. in length and operates on five bands, 80-10 meters. The 64 ft. EF-40-10-KW operates on four bands. All three models handle up to 1000 watts SSB/CW and 250 watts AM/Digital Modes. The need for an external tuner may vary based on the antenna model selected and the desired operating band. The manufacturer refers to these antennas as "End-Fed Dipoles" based upon the assertion that a "half-wave radiator is a dipole." This is a variant of the classic definition of a dipole which is a center-fed antenna with two radiating legs running in opposite directions from the feed point. Additional claims about the EFHW state that end feeding a half-wave "can energize the radiator 'nearly' as well as a center-fed." Recent anecdotal measurements indicate that the EFHW radiates about 70% as well as a traditional center-fed dipole. More information is available at each Par EndFedz® model listed below.

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.

DX Engineering Receive Short Element Active Vertical Antennas
DX Engineering Receive Short Element Active Vertical Antennas (the RSEAV Antennas) offer excellent low noise radio frequency reception from 40 kHz to 30 MHz. 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.
