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.

Transmission Lines Explained
Getting the signal from your radio to the antenna is a vital component of any radio setup, but few understand the full impact their feeder is having. This is where "Transmission Lines Explained" steps in. It provides the theory involved, through descriptions and techniques rather than mathematics. The book delivers an understanding of the theory, operation, and use of transmission lines. It examines where twin-line cable or coaxial cables are used, not only as antenna feeder cables, but also as a basis for the matching arrangement between a line and its load. Broken down into logical sections, the 136-page paperback includes examples of how transmission lines can be constructed to suit particular applications. Techniques are featured that summarize how coaxial cables can be fitted with connectors, including BNC, N and PL259 types. There is a section covering the use of the Smith Chart, where the effect of a mismatched load on a transmission line is described, including several practical examples. Of course, you'll see mathematical explanations of given situations, where necessary. Explanations of the coefficients associated with transmission lines are provided. This sets the scene to describe how a mismatch between the transmission line and its terminating load results in a reduced power transfer and its consequence, a standing wave pattern. Details are provided covering how different impedances can be matched using sections of transmission line, common mode currents, their effect and how they can be minimized using baluns. "Transmission Lines Explained" is the ideal compilation of techniques, descriptions, and examples so that radio amateurs can gain an understanding of the concepts associated with transmission lines.

DX Engineering Type F Coaxial DC Blocks
DX Engineering Type F Coaxial DC Blocks have a male F connection for the equipment and a female F connection for the antenna line. 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!
