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.

REZ Antenna Systems CM7 Common Mode Feedline Chokes
REZ Antenna Systems CM7 Common Mode Feedline Chokes are inline 1:1 common mode feedline chokes, consisting of seven mix-31 ferrite beads and RG223/U double shield coax. Proudly made in the USA, the compact and streamlined CM7 was designed to solve some of the most common issues that can negatively impact antenna system tuning and performance. For instance, common mode current carried on the outside of a coaxial cable can cause unwanted RF traveling back to your operating position, causing many issues. Another common issue is that the coax will become part of the antenna system and begin radiating RF. In most cases this is undesirable. Simply install the CM7 at the feed point of your antenna and attach your exiting coaxial cable to the opposite end. The CM7 can be used with many popular antenna types, such as EFHW, dipoles, random wires and verticals, to improve tuning consistency and antenna performance. Many antennas require the use of a 1:1 choke to isolate the coaxial cable from the antenna system for proper performance. Why not improve the performance of your antenna system? Order a REZ Antenna Systems CM7 Common Mode Choke from DX Engineering.

DX Engineering Yagi Antenna Hairpin Matching Systems
DX Engineering Yagi Antenna Hairpin Matching Systems are a convenient way to match the feed-point of a low-impedance Yagi design to 50 ohms. Then a 1:1 balun fed with 50-ohm coaxial cable may be used for optimal beam antenna performance and cancellation of RFI-causing common mode current. The DX Engineering Yagi Antenna Hairpin Matching Systems are balanced and easy to tune. They feature an upgraded electrical and mechanical design and are easily installed and tuned in as little as 10 minutes. They have enough capacity for almost any HF through 6 meter high performance Yagi design. Depending on your Yagi design, they include all of the hardware items that you need to match your Yagi antenna to a 50 ohm feed line -- without the need for drilling holes. If your Yagi does not have a split driven element (insulated from the boom), you will need to add the proper-size DX Engineering Insulated Boom-to-Element Bracket and DX Engineering Boom-to-Element Bracket Hardware Kit. Depending on the driven element diameter, you may also need DX Engineering Element Adapters. Different models cover most Yagi boom sizes and they are easily installed on the boom and fastened to the Yagi's split driven element with clamps. These same clamps may also be used for the balanced connections to the balun that handles the unbalanced coaxial cable. Hairpin Matching System Background: Many directly-fed Yagi antenna designs for HF and 50 MHz that are optimized for the best gain and front-to-back performance have feed-point impedances of approximately 20 to 25 Ohms, at resonance. Obviously, this will not allow a direct connection to a 50-ohm feedline without a serious mismatch (2:1 or more). There are various ways to match the driven element to the feed-line successfully; Gamma Match, T-Match, and the Hairpin (aka Beta Match) are favorites. The Gamma match is an outdated, unbalanced system that typically distorts the antenna radiation pattern. The T-match is basically two Gamma Match systems on either side of the boom, which may correct the imbalance, but is a mechanical nightmare and is difficult to tune correctly. In a superior-balanced Yagi feed system, the driven element must be insulated from the boom and it must be split at the boom so that the driven element halves are also insulated from each other, like a dipole. A balanced Yagi can make use of a balun for balanced distribution of RF currents and a proper, predictable radiation pattern. While the hairpin has been popular with radio operators for years, DX Engineering Yagi Antenna Hairpin Matching Systems improve on the classic design by using rods that are parallel to the boom. You can quickly match your Yagi antenna by repositioning the boom clamp and shorting bar along the boom and hairpin rods, so the antenna is easier to adjust for minimum SWR than conventional wire-loop hairpins. DX Engineering Yagi Antenna Hairpin Matching Systems also add rigidity, offer better protection against ice and wind, and add a professional appearance. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Improve your Yagi feed-point matching with DX Engineering Yagi Antenna Hairpin Matching Systems and accessories!

DX Engineering Multi-Band Dipole Antennas
DX Engineering Multi-Band Dipole Antennas are designs that are rugged, yet lightweight. Using a tuner, they are usable to 30 MHz and come complete with the wire elements, ladder feedline, center T support, and end mount brackets. These antennas are built using the highest quality components. They use 14 AWG stranded-copper, PVC jacketed elements for flexibility and strength and 100 ft. of 18 AWG 300-ohm 0.88 Velocity Factor ladder lines that are UV-resistant. Stainless steel hardware is included. Often, a 4:1 balun is suggested for multi-band dipoles; however, the best balun to use for this application is a 1:1 ratio. The 1:1 baluns provide better balance, have lower loss, and are more tolerant to load impedance and balance variations than other baluns. A tuner balun is not included in the dipole antenna kits and is available separately. The dipole center T support has pre-drilled holes for the attachment of the wire elements, feedline, and support or messenger lines. The center support top hole is used for the attachment of a "messenger line" that can be strung above the antenna wire and is used to provide support for the antenna wire and feedline. The use of the messenger line, which is strongly recommended but not included, will reduce the stress on the element wires and keep the antenna from stretching over time, which will change its resonant frequency. This line can be thin Synthetic Textile rope available from DX Engineering, which has a high breaking strength. Ideally, it should attach to the same structure used for the dipole, only above it, forming at least a 30 degree angle between the dipole and the messenger line. For further information and to decide the amount of rope you will need, please read the included instructions and check your wire antenna area of construction. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. When you lack the room for more than one antenna or need a multiband antenna for band agility, consider one of these DX Engineering Multi-Band Dipole Antennas as an elegant and economical solution!
