DX Engineering DVA Dual Vertical Array Systems
DX Engineering DVA Dual Vertical Array Systems are advanced phasing systems that have set a new standard for array performance with two ground-mounted verticals. Dual Vertical Array Systems include a compact DVA Phasing Relay Unit made specifically for an individual HF band and an EC-DVA Directional Control Console. DX Engineering Dual Vertical Arrays produce two opposite enhanced End-Fire Cardioid patterns and one Broadside-Omni pattern. Heavy-duty components handle over 2 kW continuous RF power for enhanced performance at low SWR over a wide bandwidth. The Dual Vertical Array end-fire directional patterns achieve a real front-to-back over 20 dB with typical array forward gain up to 3 dB over a single vertical. The greatest advantage of a Dual Vertical Array is that a tower and rotator are not required, as with a Yagi antenna. Especially for 160, 80, and 40, and even on the other HF bands, a Dual Vertical Array is mechanically simpler and safer. Here is a financially practical directional antenna that is much easier to install! These are great directional antenna systems for temporary and Field Day operation, as well as for permanent builds, because they ARE so much easier to install than a beam! If you are dissatisfied with your present system, are ready for an upgrade, or just need to get out of the tower game, the DX Engineering DVA is your answer!

4O3A HFC4500 Signature Series Antenna Triplexer/Combiners
4O3A HFC4500 Signature Series Antenna Triplexer/Combiners are truly a game changer for SO2R, multi-operator contest stations, DXpeditions, and Field Day operation. They allow a single triband 20/15/10-meter Yagi antenna, fed with one coaxial feedline, to be used by three stations simultaneously, with each station running up to 4.5kW. The 4O3A Signature Series Triplexer System eliminates the need for separate monoband Yagi's on the 20m, 15m, and 10m bands. Three operators, three stations, and three amps—but only one feedline and one antenna. The 4O3A HF Triplexer System uses the high-power HFC4500 Combiner, which connects to a triband 20m/15m/10m antenna, and provides dedicated ports for 20m, 15m, and 10m. Each port must be connected to a 4O3A Series S Bandpass Filter. The Combiner is not intended for standalone use.

DX Engineering 8040 NVIS Antennas
DX Engineering 8040 NVIS Antennas: Near Vertical Incidence Skywave (NVIS) is a propagation mode which uses high-angle radiation that sends signals almost straight up! They are then reflected back to Earth for very effective short to medium distance communications that works virtually every day and into the evening. NVIS dipoles are almost Omni-directional and their height requirement is for the feedpoint to be at only 15 feet above the ground! These 80 and 40 meter wire antennas work very well with their feedpoint at only 15 feet above the ground, supported by the included mast, or your own non-metallic support. The ropes tied to the wire dipole end-insulators are used as guys for the support mast, and are secured to the ground with four tent pegs. DXE-NVIS-8040S and the DXE-NVIS-8040 antenna kits are complete with everything required; the fiberglass mast (four, 4 ft. sections that extend to 15 ft.), a DX Engineering Maxi-Core® 20 1:1 Balun, model DXE-MC20-1-1T, a balun mounting kit, coax strain relief bracket, antenna wire, insulators, four tent pegs, rope, and a 100 ft. RG-8X coax assembly with PL-259s! The four legs of the antenna, each deployed 90 degrees apart, provide the mast guying. DXE-NVIS-8040SNM and the DXE-NVIS-8040NM antenna kits are exactly the same kits with everything except the 15 ft. fiberglass mast. Use your own non-metallic mast or hang the feedpoint 15 ft. above the ground from the limb of a tree. The DXE-NVIS-8040S and DXE-NVIS-8040SNM are shortened NVIS wire antenna kit version that features loading coils to make the 80 meter dipole legs the same length as the 40 meter dipole legs, 34 ft., so this antenna fits into a square area that is only about 50 ft. by 50 ft. The DXE-NVIS-8040 and DXE-NVIS-8040NM are full size, with 67 ft. wire dipole antenna legs for 80 meters and 34 ft. legs for 40 meters and it fits into a rectangular area approximately 100 ft. by 50 ft. NVIS rarely works at frequencies outside the range of 2 MHz to 10 MHz. The signal must penetrate the D layer of the ionosphere and bounce off the F layer. Signals on frequencies below 2 MHz will not penetrate the D layer; frequencies higher than 10 MHz will not bounce off the F layer at these sharp angles, they penetrate and continue out into space. Regular-height dipoles or vertical antennas have a lower take off angle and your signal may be heard three states away, but not in your own state due to the "skip zone." This skip zone is the area between the maximum ground wave distance and the shortest sky wave distance where no communications are possible. Depending on operating frequencies, antennas, their height above ground and propagation conditions, this skip zone can start at roughly 10 to 20 miles away and extend out to several hundred miles. NVIS mode of operation makes it ideal for in-state and next state communications during disasters or other emergency situations. The military has used NVIS techniques for decades to provide short haul communication with other units on the ground. This is why these antennas are ideal for round-table gatherings with regional ham friends on 40 and 80 meters, day to day and night after night. These antennas are easy to deploy and are great for camping, RVs, QRP, ARES, EMCOMM, State QSO Parties and Parks On The Air (POTA) and any other uses where short range HF operation on 80 or 40 meters is desirable. They are actually pretty stealthy, too! Due to their near vertical radiation, NVIS dipoles are almost Omni-directional. They even have a legal-limit power rating! Remember, Amateur Radio operators look to 80 and 40 meters for short skip NVIS operations. Order DX Engineering 8040 NVIS Antennas and fill in the skip zone!

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.
