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.

WiMo X-Quad Antennas
WiMo X-Quad Antennas, with separate monoband models for 144-146 MHz or 430-440 MHz, represent a refinement of VHF and UHF cross-polarized Yagis. They are well-known in Europe as "multi-element quads"—an antenna with aluminum elements, not a wire and fiberglass antenna—which offer excellent gain with a relatively short boom length. X-Quads are a great solution due to their short length and lightweight construction, especially for VHF/UHF satellite systems which require rotation in all compass directions and elevations. Two X-Quad Antennas, one for 144-146 MHz and one for 430-440 MHz, may be mounted at opposite ends of an azimuth-elevation rotator cross-boom for high-performance full duplex Satellite operations. For either or both bands, X-Quad Antennas may instead be used in a stationary mount, as pictured, for all-mode terrestrial operations. In either application, multiple X-Quad Antennas may be stacked vertically and horizontally for additional gain and tighter patterns. The WiMo X-Quad special features, developed specifically for Satellite Amateur Radio include: * Switchable Polarization Plane; horizontal/vertical/right hand circular/left hand circular (remote switching requires optional equipment) * High gain compared to other antenna forms due to the "stacking effect" * Short boom length and compact design * Back-end boom or mid-boom centered mounting to the mast is possible The radiator element is a "stacked quad" multi-element beam, for which linear polarization can be compared to a crossed slotted radiator. However, the advantage of the X-Quad is that it can be optimally used for the desired polarization by simply changing the feed. Compared to a typical cross-polarized Yagi, all directors and reflectors are active in the X-Quad, which enables the compact design. As with cross-polarized Yagis, switching is accomplished on the mono-band X-Quad either by a coaxial relay or with a band specific WiMo Remote Polarization Switch (sold separately). If the remote switch is mounted at the antenna, then only one coax cable and a 4-conductor control cable are required, sold separately. If the Switch is used at the station, then two coaxial cables from the antenna to the station are needed. The WiMo X-Quad Antenna can also be permanently set for circular operation by using an optional, band-specific Phase Line. The secondary elements are arranged diagonally in relation to the square-shaped driven element, which corresponds to the voltage distribution on the radiating element, for the most favorable results. In comparison to Yagi antennas, the X-Quad pattern and tuning are affected less by the influence of external fields, making them ideal for installation under a roof, in an attic space. All elements are electrically conductively connected with boom and cable outer sheath, thus eliminating interference from atmospheric noise. Two Type-N female coaxial connectors, one for each polarization, are mounted in a housing that is waterproof. Boom and elements are made of aluminum, all hardware is stainless steel. Construction and design of the antennas are protected by law (DBGM). The antennas are designed for boom-end mounting; however, alternatively the mast clamp can be mounted in the middle of a non-metallic boom. These antennas have a split boom, so their transport length is only 29.53 in. (75cm) for the 2m antenna and 25.59 in. (65cm) for the 70cm X-Quad. For portable operations they can be stowed away comfortably in the trunk of car and their shipping costs are comparatively low.

SSB Electronic Mast-Mount Preamplifiers
SSB Electronic Mast-Mount Preamplifiers are low-noise, band-specific, weatherproof preamplifiers designed for installation near VHF and UHF antennas. Available for the 6 meter, 4 meter (Europe), 2 meter and 70 cm Amateur bands, these preamplifiers are installed in-line, at the antenna. They improve receive performance by amplifying weak signals before feedline loss can reduce them. Powering and Sequencing Most models can be powered remotely through the coaxial cable, and many modern transceivers include a built-in bias-tee for mast-mounted preamplifiers. If the transceiver or transverter system does not provide power, an external bias-tee or remote-feed unit is required. • The DCW-15 and DCW 2004B provide sequencing support. • The DCC-12 does not provide sequencing. • SP series preamplifiers include a built-in RF VOX circuit for safe operations up to 100 watts; for transmit power above 100 watts, PTT control with a sequencer is required. Some models require a direct DC connection (UHF female). • -S series preamplifiers feature lower current signal relays with slightly higher insertion loss. • MHP and MHP-S series preamplifiers versions require sequencer control (see below). Signal Filtering and Switching Built-in helix filters effectively reject out-of-band signals, helping maintain clean receive performance. Real coaxial relays handle transmit/receive switching, resulting in very low insertion loss (except for SP-S series). And each amplifier is carefully calibrated at multiple test stations before packaging. Dual-Band Models Dual-band models include built-in diplexers, so they require only one connection for the multiband antenna and one connection for the station coaxial cable. MHP Series for Demanding Stations The MHP series is designed for demanding operating environments and provides higher gain for weak-signal modes such as Tropo-DX and EME. With maximum transmit power handling of 1500 watts on 6m and 2000 watts on 2m and 70cm, these preamplifiers are well suited for contesting, DX, and EME operation. Important Note for MHP Models Bias-tee power (on the RF coax) is not supported in most MHP Preamplifiers. They must be powered directly using the appropriate cable size for the required distance, and they may only be operated with a correctly wired sequencer, such as the DCW 2004 B Sequence Controller. Transmitting high power without a directly wired sequencer is likely to damage the MHP preamplifier. Housing and Hardware All SSB Electronic Mast-Mount Preamplifiers are supplied in UV-resistant, weatherproof housings with Type N female connectors. Hot-dip galvanized clamps and stainless steel mounting hardware are included. See individual models for band coverage and detailed specifications.

Create CLP-5130-2N VHF/UHF Log-Periodic Antennas
Create CLP-5130-2N VHF/UHF Log-Periodic Antennas are high-gain, wideband directional beam antennas. Designed for horizontal polarization, they may also be mounted vertically with user-supplied hardware. These antennas are capable of transmitting on all amateur bands from 2-meters through 23-centimeters at 500 watts power! Forward gain from 105 MHz to 1,300 MHz is 11 to 13 dBi, depending on the frequency. They present an SWR of less than 2.0:1 across their entire 1,195 MHz range of operation. They are also suitable for use in scanner listening, VHF/UHF television, aviation band, government communications, and business-band radio. These log-periodics use a specially shaped aluminum boom that allows for movement of the phasing line. Additionally, distortions in the vertical and horizontal planes have been minimized and adjustment of the element-alignment is unnecessary. This results in a more uniform radiation pattern when compared to similar antennas. Create Log-Periodic antennas are very easy to assemble when compared to other log-periodic designs. Quality is seen everywhere… even the boom-to-mast bracket is made of a rugged magnesium alloy. A Type N connector is employed for maximum signal transfer at high UHF frequencies. To fully utilize the bandwidth of these antennas requires a high-quality coax, like DXE-400MAX or LMR-600. If you don't have the space or resources to put up several VHF and UHF antennas, Create CLP-5130-2N VHF/UHF Log-Periodic Antennas are truly your one-antenna solution to VHF/UHF operation up to 23 cm!

DX Commander Venture HF Multi-Band Vertical Antennas
DX Commander Venture HF Multi-Band Vertical Antennas are designed for portable operation. The design is built on the proven success of other DX Commander antennas but optimized for portable operation. Efficiently resonant on 40, 20 and 15 meters, the DX Commander Venture is designed for some of the most popular bands for portable operation. Using the same principals as a fan dipole, with several vertical wire elements of various resonant lengths attached to a common feedpoint. The Wire elements and any supporting ropes are arranged on spacer plates with "speed slots" around the non-conductive fiberglass mast. When a proper radial system is attached to the radial plate, the Venture will achieve quarter-wave vertical performance with natural resonance and low SWR on the bands it's configured for with no antenna tuner required. Band hopping DXing and simultaneous multi-band multiplex operations are supported. The Venture is rated at 1500W SSB/CW, 400W FT8 and other digital modes. The Venture antenna is only 23 feet (7 m) so setup is a cinch in the field. SWR bandwidth is typically 300 kHz on the bands the antenna is cut for. The Venture, while being designed for 40, 20 and 15 meters, can be used on 10 and 6 meters with an antenna tuner. DX Commander Venture Features and Specifications: Ground Post: Supplied with a Fiberglass Ground post. Alloy Plates: Aircraft quality 5251 alloy, laser cut in England before deburring to give that "hammered" look, which eliminates sharp edges and provides a nice finish. Spreader Plates: Marine-grade high-density polyethylene sheet material from USA, charcoal-gray, UV and environmentally stabilized to withstand the harshest of marine and high RF conditions. Spreader Plates are machine cut in England to DX Commander specifications. Shock Cord: Marine Grade shock-cord, with a UV and RF stable Dyneema woven exterior. Hardware: Kit includes Stainless Steel bolts, wing nuts, and spade connectors. Coaxial Connector: UHF Female SO-239 coaxial connector, nickel plated brass with PTFE dielectric. Fiberglass Poles: Made to DX Commander specifications in a spiral wound fiber, high-quality epoxy and paint finish. DX10 Wire: Made in England for DX Commander, DX10 wire has an outstanding reputation for both strength and in particular, extreme flexibility. The insulation is "arctic grade" and still flexible down to -40° F. Originally designed for military use, this insulation is particularly strong but highly flexible and the stranded annealed copper wire is approximately 19 AWG and is made from 24 strands of 0.008 in. (0.2mm) wire. All DX Commander Venture Antenna Kits come with everything you need (except the patio): • Rapide2 Mast – 23 ft. (7m) Extended Height • Supplied with a 1.50 in.

DX Engineering Reversible Beverage Systems
DX Engineering Reversible Beverage Systems basically allow two Beverage antennas to be switched to receive in opposite directions while sharing the same physical space. DXE-RBSA-1P Reversible Beverage Systems antennas provide two opposite "end-fire" directional patterns with excellent front-to-rear directivity and superior signal-to-noise ratio as compared to transmitting antennas. Dramatically improved long distance weak signal results may be achieved on MW and the 160, 80 and 40 meter bands, including shortwave bands, with receive-only Beverage antennas using wires that are typically only 350 to 800 feet long, depending upon the band of interest. The two-direction DXE-RBSA-1P Reversible Beverage Systems offer a space and installation advantage because two opposite single-wire Beverage antennas would require twice the length. DX Engineering Reversible Beverage Systems are immune to the strong signal overload and core saturation common in multi-transmitter contesting environments and are used by winning contest stations and low-band DXers around the world. These Reversible Beverage antennas have two "F" connectors; one "Away" port for the default end-fire receiving pattern off the end of the wire, and one "Toward" port for the opposite direction. The standard configuration of these systems has the "Toward" port terminated (75-ohm termination included), so both antennas share a common feedline. Applying a negative 10 to 18V DC to the feedline switches the system between the two antenna ports for reception in opposite directions. For simultaneous reception from opposing directions, each of the two feedlines can be run to separate receivers, with the termination load not used. You can build a 4-direction receive antenna system with two DXE-RBSA-1P Reversible Beverage Systems and one DX Engineering RLS-2 Two-Port Receiving Switch that also requires only one feedline! The optional DX Engineering Feedline Voltage Coupler, model DXE-FVC-1 is highly recommended to provide all of the required feedline voltage injection. Plus, the optional DXE-EC-4 BCD Control Console completes the system for four-direction switching right in the shack. DX Engineering Reversible Beverage Systems are optimized to use our optional 450 ohm ladder line for the antenna element. We strongly recommend using that type of "window line" because the consistent spacing of the antenna wires will produce the best operational results. However, the RBS will work with any 300-600 ohm 2-wire line. For best feed line results, DX Engineering highly recommends using our high quality flooded or quad-shielded 75-ohm coax with F-type compression connectors to ensure a weatherproof installation. Additional features include: * Broad operating range, 0.2 to 30 MHz * Fully isolated grounds prevent common-made noise and unwanted signals * 75 ohm design enables the use of high quality, low cost cable and connectors * RF shielded housing used for isolation and improved life * Directional Switching Voltage: nominal 12V AC or negative 12V DC, feedline injected * Directional Switching Current: less than 80 mA * Antenna impedance: 300-600 ohm (450 ohm recommended) * Feedline impedance: 50-75 ohm (75 ohm recommended) * RBSA-1FP Feed Point unit dimensions: 5.5 in. width x 3.5 in. depth x 1.5 in. height * RBS-1RT Reflection Transformer unit dimensions: 2.125 in. width x 2.125 in. depth x 1.125 in. height Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. DX Engineering Reversible Beverage Systems offer the best DX reception and flexibility in high performance two-direction wire Beverage receive antennas. Get yours set up soon!
