Comet Antennas No-Hole Fender Brackets
Comet No-Hole Fender Brackets are vehicle-specific truck and SUV mobile antenna brackets that mount without drilling. Unlike lip-mounts that use set screws and penetrate the paint; these brackets use bolts that already exist on your fender. Due to the particular vehicle-specific angles necessary to form these brackets, almost all are designed for the driver's side only. (There are only a few new right fender mounts!) By using an existing fender bolt, the bracket extends between the hood and fender gap. The mounted antenna sits vertically, along the side of the hood. A 3/4 in. hole in the bracket accepts the standard NMO connector and cable assembly. You may also use these brackets to attach an antenna that has a UHF mount. Simply choose a Comet UHF mount cable assembly; they include a large washer and jam nuts to keep the 5/8 in. diameter UHF connector from falling through the 3/4 in. hole in the bracket. NOTE: * Coaxial cable and base mount assemblies are not included with these brackets. * Not suitable for larger antennas which require the use of a heavy duty bracket. These clever mounting brackets provide a stable antenna platform without drilling holes in your vehicle. Order your Comet No-Hole Fender Brackets from DX Engineering and enjoy mobile operating again!

Mastrant Antenna Support and Guy Line Ropes
Mastrant Antenna Support and Guy Line Ropes are available in several sizes and strength ratings, perfect for support of wire antennas, vertical antennas and antenna masts, as well as support of Yagi booms and elements. Mastrant ropes are of the highest quality for strength and are UV-protected for extended longevity. MASTRANT-O is a highly reflective rope (bright orange plus braided reflective tape) based on long-term proven Polyester (Dacron) product line. It is designed for maximum visibility in public places such as Field Day and POTA activities. Like all Mastrant ropes, it is UV stable and resistant to all weather conditions. It has low weight, great abrasion resistance, great durability and is nonconductive (no effect whatsoever on your antenna). Moreover, in contrast to ropes made from aramid fibers (Kevlar, Vectran, Technora, Twaron), it has knot strength about 60 %. Mastrant-P and Mastrant-R Ropes are stronger than other synthetic ropes of the same size, made from proven modern polyester. Mastrant-Q is a new rope made from a blend of polyester and polypropylene, designed specifically for guying applications. It offers an excellent performance-to-price ratio and has a knot strength of approximately 60%. It replaces Mastrant-P in diameters of 6 mm (1/4 in.) and larger. Mastrant-S is a similar polyester/polypropylene rope, distinguished by its highly reflective strands for increased visibility. Mastrant-M is their highest strength rope with the Dyneema® DM20 core, a superior synthetic rope offering high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance are all attributes that make Mastrant-M the best rope for guying. Larger, stronger sizes of Mastrant-M are used in Europe and other parts of the world for tower guying. Durability and safety are of prime concern to ensure that an antenna installation remains fully operational for a long time. Antennas and guy lines are exposed to changing weather conditions, mechanical strain, UV radiation, humidity, and more. These non-conductive synthetic fibers have all the necessary qualities: high strength, negligible stretch but good flexibility, long life, low moisture collection, fast drying, a minimum bending radius adding the ability to tie knots, good UV radiation resistance, weather durability and resistance to acids and alkali. Conversely, steel guying wires are heavy, difficult to work with, and their strength deteriorates with time due to corrosion and general aging. Electrical conductivity of steel guys is an undesirable feature, as they interact with the antennas and adversely modify radiation patterns. Thanks to recent developments in synthetic materials, both amateur and professional users are changing over to non-conductive guys and ropes. Mastrant offers these products for a variety of applications, from thin support lines used for wire antennas and beams, to rope guys for supporting small and portable masts and vertical antennas. When you need quality rope to install, replace, or modify your antenna systems, consider Mastrant Antenna Support and Guy Line Ropes, now available from DX Engineering.

DX Engineering TWIG End Fed Half Wave QRP Antenna Feedpoint Kits
DX Engineering TWIG End Fed Half Wave QRP Antenna Feedpoint Kits are a compact, essential component for building a low-power (QRP) end-fed half-wave antenna system. Perfect for portable operations and outdoor activities such as POTA® or SOTA™, this feedpoint kit simplifies setup while delivering reliable performance. The TWIG is rated for 25W SSB, 10W CW, and 5W Digital modes, delivering an SWR of less than 2:1 without an antenna tuner. At its core, the TWIG features a 49:1 transformer that matches the impedance of the user supplied half-wave element wire to 50-ohms, ensuring compatibility with most QRP transceivers. The BNC female connector pairs easily with recommended coax cables, and when the element wire is properly tuned, no external tuner is required—reducing the amount of gear you need to carry. The kit includes a built-in quick connector designed for 24/26 AWG antenna wire, making element installation fast and secure. Two end insulators and clips are also provided, ensuring reliable strain relief and easy attachment of the antenna wire in the field. Installation is quick and straightforward, allowing you to get on the air fast and start making contacts. No additional counterpoise wire is necessary; the coax cable serves that function when installed correctly. For best results, use optional 24/26 AWG wire such as CEW-VIZ24-YEL100, a high-visibility, PVC-insulated stranded copper wire. A typical setup uses a sloper configuration, with the feedpoint about 6–7 feet above ground and the wire sloping upward to 25–30 feet. Recommended coax length is 25–35 feet with BNC connectors and adding an optional DXE-LPFC-BNC Feedline Choke at the transceiver end is suggested. While the antenna supports multiple configurations, wire length will vary based on installation.

United Microsystems BT-75/BOG Beverage-On-Ground Antenna Transformers
The United Microsystems BT-75/BOG Beverage-on-Ground (BOG) Antenna Transformers are specifically designed for Beverage-on-Ground receive antennas and is based on the proven BT-75 transformer used with elevated Beverage antennas. Because BOG antennas are installed directly on or just above the ground, they require no supports and can be significantly shorter than traditional Beverage antennas, making them a practical option where space is limited. BOG antennas typically exhibit lower impedance than elevated Beverage antennas. The BT-75/BOG is optimized to provide proper impedance matching between the antenna and 75-ohm RG-6 coaxial cable, improving performance compared to standard Beverage transformers. For correct operation, the far end of the antenna must be terminated with a 250 to 300-ohm resistive load. The United Microsystems RXT-270 termination resistor is recommended. Properly installed Beverage antennas are low-noise, receive-only antennas that provide excellent rejection of signals and noise from the undesired direction. Due to the lower velocity factor of radio waves near the ground, a BOG antenna can often deliver a radiation pattern similar to an elevated Beverage antenna of roughly twice the length, though with reduced signal strength. A BOG antenna as short as 150 to 200 feet can provide effective receive performance, although a preamplifier may be beneficial in some installations. The BT-75/BOG is designed for use with 75-ohm RG-6 coaxial cable. Originally developed for television applications, RG-6 offers low loss at VHF and UHF frequencies, resulting in extremely low loss on the 160, 80, and 40-meter bands. Its availability and low cost make it a popular choice for low-band receive antenna feed lines. The transformer is housed in a NEMA-rated enclosure with stainless steel hardware for long-term outdoor durability. A built-in gas discharge tube across the antenna terminals helps protect the transformer from nearby lightning-induced surges, although it will not provide protection against direct or very close lightning strikes.
