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.

The REZ [Z]-17SS Stainless steel whips are 17-foot-long telescopic whips that collapse down to 24 5/8in. Weighing in at 14.4 oz, with a power rating of 1000W PEP, these 17-foot whips are resonant on 20-6 meters by themselves or up through 40 meters with the addition of an XFORM UNUN. The REZ CM7 Common Mode feedline chokes provide a reduction in common mode current that travels back down your coax and causes issues for radiating your signal. These quality feedline chokes help keep the RF radiating from the antenna where you want it and not the coax. The REZ Ranger Pro Backpacks provide a convenient way to carry your REZ antenna system and ancillary gear into the field. Depending on the size of your radio and battery, you may be able to carry your entire portable setup in this backpack. This quality pack makes it easy for organization of all of your portable gear with multiple pockets and Molle webbing for additional attachment points to hold your gear.

Diex Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles
Diex Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles offer high performance multi-band HF operations, and they are an excellent choice where there's not enough space for a full-size dipole or Yagi. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotating mast, these unique multi-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. DIEX Antennas Multi-Band Trap Shortened Rigid Rotatable Dipoles power handling is 1500W PEP SSB, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that a directional HF antenna should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.

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.

This model (ESB-5059) can switch two antennas to one feedline, or it can be used to switch between horizontal and vertical polarization on a cross-polarized Yagi or X-quad. Featuring high power handling, very low in-line attenuation and SWR, and simple 13.8 VDC operation, the AS-3000 is an excellent addition to any VHF, UHF or SHF station. The solid aluminum chassis incorporates a mounting bracket for a 1.5 to 2.3 in. mast clamp, with three downward facing Type-N female connectors, for the default normally closed (NC) port, a normally open (NO) port and the common port. A 4-pin DIN with mating connector is used for direct DC control of the relay, and a user supplied shielded control cable is recommended to prevent RF induced false keying. The AS-3000 supports the use of short lengths of coaxial cable for mast mounted equipment to dramatically reduce losses. Coaxial lines used with this switch and antennas should be calculated and tailored so that they do not cause an impedance transformation. Specifications of the AS-3000 Mast Mount Antenna System Switch (ESB-5059): Frequency range: DC – 3000 MHz Switch positions: 2 Insertion loss, typ.: 0.01 dB / 150 MHz 0.02 dB / 500 MHz 0.025 dB / 1000 MHz 0.03 dB / 2000 MHz < 0.1 dB / 3000 MHz Isolation: >60 dB / 2,5 GHz VSWR: <1.2 : 1 RF Power Handling, by band: 1000 W/2m; 800 W/70cm; 500 W/23cm; 250 W/13cm RF Connectors: Type-N female Direct DC Control Input: 4-pin DIN (mating connector provided) Switching Voltage: 13.8 VDC @ 250mA, max.

Create CLP-5130-1N VHF/UHF Log-Periodic Antennas
Create CLP-5130-1N 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 6-meters through 23-centimeters at 500 watts power! Forward gain from 50 MHz to 1,300 MHz is 10 to 12 dBi, depending on the frequency. They present an SWR of less than 2.0:1 across their entire 1,250 MHz range of operation. They are also suitable for use in scanner listening, VHF/UHF television, FM broadcast, aviation, government communications, and business-band radio. To fully utilize the entire bandwidth of these antennas requires a high-quality feedline, like DXE-400MAX or LMR-600. 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 rugged magnesium alloy. A Type N connector is employed for maximum signal transfer at high UHF frequencies. If you don't have the space or resources to put up several VHF and UHF antennas, Create CLP-5130-1N VHF/UHF Log Periodic Antennas from DX Engineering are truly your one-antenna solution to VHF/UHF operation!
