DX Engineering 450 Ohm Ladder Line
DX Engineering 450 Ohm Ladder Line is a transmitting grade low-loss parallel-wire RF feedline featuring a strong, waterproof, UV black polyethylene insulation. To maintain the wire spacing between the conductors while reducing losses, the integral flat plastic material alternates with rectangular openings, which explains the "Window Line" nickname. Capable of handling over 3 kW of RF power, DXE-LL450 is a very low-loss transmission line across HF. It is ideal for exceptionally long feedline runs and for low band wire antennas operated on multiple bands on which the feedpoint impedance can vary significantly, causing mismatch and elevated SWR. Unlike coaxial cables, DX Engineering DXE-LL450 Ladder Line maintains low RF losses at frequencies where antenna feedpoint impedance mismatches cause high SWR. It can provide significantly higher efficiency than coaxial cable when feeding non-resonant antenna systems that are matched with a wide impedance range antenna tuner. DXE-LL450 450 Ohm Ladder Line is a high-quality flat RF feedline, about 0.938 in. wide (15/16") with two 16-gauge copper-clad steel wire conductors (29 AWG x 19 strands) that provide the strength to hold up for long spans between supports without twisting. It exhibits a nominal impedance of around 400 Ohms and a nominal Velocity Factor of 91 percent. For proper performance, LL450 Ladder Line must be installed suspended through the air supported by insulators every 25 ft. or less, kept at right angles and several inches away from other wires, and at least one foot away when run parallel to the earth or large metal surfaces. Installing with an axial twist of one turn per 10 ft. can reduce wind, rain and ice loading, RF coupling and RF noise. DXE-LL450 can be mounted with insulators and suspended on metal or wood posts or run along a wood fence line, only if the fence has no wires or metal mesh that couples RF noise or unbalances the feedline. Often used for non-resonant wire doublet antennas, DXE-LL450 can be more easily terminated outdoors to a DXE-MC20-C4-1 4:1 Balun or a DXE-MC20-1-1T 1:1 Balun. Then, with no inline switches or relays, directly connect the antenna system to a typical indoor wide range antenna tuner using a solid dielectric coax, not foam dielectric, to handle high voltage at high SWR. DXE-213U or DXE-214 Coaxial Cable Assemblies 12 or 18 ft. with PL-259s are perfect for this method, which eliminates the need for a special balanced tuner, and avoids the losses and detuning effects caused by unbalancing when ladder line is routed indoors near wires and ducts. DXE-LL450 is sold by the foot, previously sold as DXE-LL450-CTL, this is the same ladder line with a new part number. It is also available in spools of 500 ft. DXE-LL450-5C and 1,000 ft. DXE-LL450-1K, which are specified for DX Engineering Reversible Beverage System Antennas. NOTE: This type of feedline is intended for MF and HF use and is not suitable for use above 54 MHz. Also consider DX Engineering 300 Ohm Ladder Line, DXE-LL300, an excellent alternative low-loss HF feed line that reduces impedance extremes on non-resonant HF multiband antenna systems.

DX Engineering Receive Short Element Active Vertical Antennas
DX Engineering Receive Short Element Active Vertical Antennas (the RSEAV Antennas) offer excellent low noise radio frequency reception from 40 kHz to 30 MHz. Better receiving performance than full-size transmit antennas and other active makes the DXE-RSEAV-1 the best choice on the market for VLF through HF reception, including long-distance AM broadcast, Medium Wave and Shortwave (SWL), and new low-frequency Amateur bands, DXing, contesting, and everyday HF operations. Click on a listed product title and Scroll Down to see additional important information. A complete product description appears below the Specifications Overview. Instruction manual links appear in the Documentation section. The sleek and stealthy DXE-RSEAV-1 includes a high-quality three-section 8.5 ft. (2.6m) aluminum tubing whip, insulated mounting plate and the completely new DXE-AVA-3 Active Matching Unit. Its state-of-the-art broadband operational amplifier design works as a high-impedance buffer between the short antenna element and RG6U 75-ohm coax. When installed in the appropriate location, RSEAV antennas provide significantly better weak signal reception than other active receive antennas and full-size transmit-capable antennas, with substantially reduced noise and lower spurious signal interference. Receive Short Element Active Vertical Antennas are intended to be mounted on a ground rod at ground level in a clear area away from all metal, towers and other antennas. They are sold individually (DXE-RSEAV-1), or with a bias tee (DXE-RSEAV-1FVI) and DXE-RSEAV-1 Receive Short Element Active Verticals set a new standard for "Active Receive Vertical Antennas" replacing legacy DXE-ARAV-3, ARAV-2, ARAV-1 and AL-24 versions. Use multiple DXE-RSEAV-1 for all 4 and 8 element DX Engineering Receive Arrays – all 3, 4 and 8 element Hi-Z Antennas Arrays – and 2 element receive arrays with DXE-NCC-2 and NCC-1 Variable Phasing Controllers. The DXE-RSEAV-1 is designed to be a very low-gain, low-noise antenna for greatly improved signal-to-noise performance over a very wide range of frequencies. In a proper single or multi-element array installation, this Receive Vertical antenna will attenuate high-angle skywave signals, which is the goal for a low band DXing receive antenna. Low-angle, long-range DX signals are easier to copy with a good radio and DX Engineering Receive Short Element Active Vertical Antennas. Please Note: To achieve the expected reception pattern, multi-element phased arrays depend upon identical gain and phase response from each element. Every individual element amplifier, its grounding, and even its feedline characteristics and length, must be identical to the others in the array. Therefore, when unrepairable failures occur, it is essential to replace or upgrade all the elements in the array with identical, fully compatible DXE-RSEAV-1 antennas or DXE-AVA-3 units.

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 Receive 8 Circle Array Controllers
DX Engineering RCA8C-1 Receive 8 Circle Array Controllers are the highly sophisticated switch controller relay units from the Eight Circle Array Systems--the receiving systems that use time delay phasing--rather than the conventional narrow-band, frequency-dependent phasing, to provide eight 45 degree spaced directional patterns. The RCA8C time delay phasing is directivity-optimized to produce wider and deeper rear nulls and a narrower main lobe. The result is that noise and undesirable signals are greatly reduced for a superior front-to-rear ratio (F/R). Better control of phase and currents provides a cleaner pattern with the Receive 8 Circle than is available with vertical antenna transmit arrays. DX Engineering Receive 8 Circle Array Controllers are designed to be used with eight identical vertical active or passive vertical elements, symmetrically spaced in a large circle, to provide switching for an 8-direction receiving antenna system. Passive elements will generally provide you with a monoband receiving system. Finally, these systems offer greater reliability in receiving applications. Receive Eight Circle Array Controllers use sealed relays sized for receiving applications with silver contacts to prevent oxidation and contamination. Most transmitting four-square switches use large open-frame relays where the contacts are exposed to the air, which can lead to contamination. Relays with brass contacts can oxidize, leading to poor conductivity. Receive Eight Circle Array controllers feature: * W8JI design * Operation from 100 kHz to 30 MHz * Excellent directivity for better signal-to noise ratio * Switching console provides eight 45 degree spaced directions * Less physical space and maintenance required than phased Beverage antennas * Low current DC powered control console allows system operation without AC power mains The optional DX Engineering Eight Circle Receive Short Element Active Vertical Antenna Package, DXE-RSEAV-8, offers excellent receiving performance from 100 kHz to 30 MHz, while using only a 8.5 ft. (2.6m) aluminum vertical antenna elements. A unique design makes the Receive Eight Circle Array System vastly superior to traditional active vertical antennas in both strong signal handling and feedline decoupling. This results in significantly better weak signal reception due to lower spurious signal interference and reduced noise. DX Engineering RCA8C Receive 8 Circle Array Controllers are the foundation of your Eight Circle Array!

DX Engineering Tinned Copper Radial Wire Kits
DX Engineering Tinned Copper Radial Wire Kits include plentiful quantities of biodegradable staples and tinned crimp ring terminals that are easily soldered. Along with spools of the same wire as used by the most successful contest stations and DX enthusiasts for their ground-mounted vertical antennas, these kits will help your antenna system achieve optimal performance. The 16 AWG tinned solid copper wire in these kits provide an extremely cost effective solution for the high-count, full-size ground radial wire systems that are required for top-performing HF vertical antenna installations. Ground wire radials do not need to be any specific length because the earth detunes them. Fill your ground-mounted vertical space with radials that run out from the antenna feedpoint in all possible directions, as far as they can go, up to about one-quarter wavelength on the lowest frequency. Even radials that are all about one-eighth wavelength long on the lowest frequency band are just fine for multi-band verticals over reasonably conductive soils. Use longer radials on lossy soils with sand and rocks. In most cases, a greater number of short ground radials will provide greater efficiency and stronger signals than is achieved with a few long radials. DX Engineering Tinned Copper Radial Wire Kits are available in four sizes: Shorter spool kits, 500 ft. and 1,000 ft., are perfect for the single HF ground-mounted vertical. Longer spool kits, 2,500 ft. and 5,000 ft., are intended for 2-element Dual Vertical Arrays, 3-element ProStack Arrays, and 4-element Four Square Array Systems. Each kit has the appropriate number of biodegradable staples and tinned crimp ring terminals. Why is this wire the absolute best choice for any ground-mounted vertical antenna? Because, DX Engineering Tinned Copper Radial Wire will last much longer in a variety of soil conditions as compared to bare copper, copper coated steel or aluminum wires. Radials deployed with those other wire types actually corrode and degrade rather quickly. Unfortunately, they do so slowly enough that the operator does not easily perceive that degradation in terms of antenna system performance. With Tinned Copper wire, full radial system integrity is maintained for a greater number of years. Depending upon soil type, installations with DXE-TCRW16 will maintain vertical antenna performance for many, many years… and even decades. NOTE: To prevent accelerated corrosion and the possibility of noise, DO NOT use metal anchor pins (lawn staples) on Tinned Copper Radial Wire. These kits contain only the DXE-STPL-100BD Biodegradable Anchor Pins to hold down bare wire radials. Biodegradable staples allow easy installation of radial wires and will disperse in a couple years, after they are no longer needed, making them site friendly. Biodegradable staples work best in soft ground where they may be pushed or lightly tapped into the ground. Since they are a lacto-resin material they are subject to breaking in rocky or hard soil and are not intended to be hammered. DX Engineering Tinned Copper Radial Wire kits are the right choice for long lasting top-performance radial systems for your ground-mounted vertical antenna system.

The patented DXE-RFS-3 DX Engineering Receive Four Square Array Controllers are the heart of a sophisticated receiving system that uses time delay phasing rather than the conventional narrow-band, frequency-dependent phasing systems. The time delay phasing is directivity-optimized to produce wider and deeper rear nulls and a narrower main lobe. The result is that noise and undesirable signals are greatly reduced for a superior front-to-rear ratio (F/R). Better control of phase and currents provides a cleaner pattern than those found on available transmit four square arrays. The RFS-3 DX Engineering Receive Four-Square Array Controllers are the switch relay units that are optimized to use the DX Engineering's Active Vertical Antenna Package DXE-ARAV4-4P of four active verticals. These products together offer great F/R response over octaves of bandwidth. DX Engineering's Active Receive Antenna System offers excellent receiving performance from 100 kHz to 30 MHz, while using only a 8.5 ft. antenna element. A unique design makes it vastly superior to traditional active antennas in both strong signal handling and feedline decoupling. This results in significantly better weak signal reception due to lower spurious signal interference and reduced noise. Finally, these systems offer greater reliability in receiving applications. The RFS-3s use sealed relays sized for receiving applications with silver contacts to prevent oxidation and contamination. Most transmitting four-square switches use large, open-frame relays where the contacts are exposed to air, which can lead to contamination. Relays with brass contacts can oxidize, leading to poor conductivity. Advantages of the RFS-3 Receive Four-Square Antenna Systems over other small or medium-size receiving arrays include: * Reduced susceptibility to high angle signals compared to EWE, Flag, Pennant, and K9AY antennas * Excellent directivity in a small space for better signal-to-noise ratio * Switchable in four 90 degree spaced directions * Directivity over a very wide frequency range using DX Engineering DXE-ARAV4-4P active elements * Less physical space required than a Beverage antenna, and active elements need only a minimal ground system * Enhanced relay contact reliability

DX Engineering Insulator and Bent Pin Shackles Kits
DX Engineering Insulator and Bent Pin Shackle Kits are used for guy line attachment to towers for Amateur Radio and commercial applications. Insulated attachments prevent RF noise that can be created by Two kits are offered that include three Insulators of either size and three Bent Pin Shackles. The included porcelain guy strain insulators are commonly known in ham radio tower work as the "502" or the "504" so that is how these insulators are numbered. They have the mechanical strength of 10,000 pounds and 12,000 pounds, respectively. Each accepts big grip dead ends for either metallic or non-metallic guy lines. Also known as a clevis in the power industry, Bent Pin Shackles are specially designed with a removable bent bolt and locking nut to go through the outer hole of the matching insulator. Forged from 1/2 in. steel and hot dip galvanized, these shackles have a minimum ultimate strength of over 12,000 lbs. and have a rounded end that is large enough to be used around a tower leg. However, the assembly of the guy line and these insulated attachments are typically connected to a tower ear or guy bracket with a screw pin shackle used as a link. Order one DX Engineering Insulator and Bent Pin Shackle Kit for each level of guying. For those who already have insulators, Bent Pin Shackles are also available without insulators, in a set of three. Look to DX Engineering for the high quality and unique tower hardware that you need.

DX Engineering NCC-1 Receive Filter Sets
DX Engineering announces a series of NCC-1 Receive Filter Sets, a breakthrough option for owners of the NCC-1 Receive Antenna Phasing Unit. These advanced plug-in filter module sets offer frequency-specific receive antenna system enhancements for the NCC-1. All filter modules sets are available in matched pairs of low-pass, band-pass and high-pass frequency ranges. Filter cut-off and center frequencies correspond to the major Amateur bands, 160, 80, 40, 20, 15 and 10 meters, with filter module insertion loss of only about 1 dB. Highly regarded by many owners and engineers to be the best receive phasing and noise canceling unit available, the DX Engineering NCC-1 is used extensively by enthusiasts in Amateur Radio DXing, Contesting, AM DXing, and Short-Wave Listening (SWL), and is also used in commercial AM and HF broadcast applications. DX Engineering NCC-1 Receive Filter Sets add a new dimension of functionality to the NCC-1, for advanced directional noise and signal nulling performance, enhanced with specific frequency range operations. By default, NCC-1 filter slots are jumpered to pass all signals. On the NCC-1 front panel, the BAND toggle switch "L" or "H" positions each activate one of two filter pair slots, allowing over 360 degrees of phase rotation in two frequency ranges. The BAND switch "L" position covers from 850 kHz to 8 MHz. The BAND switch "H" position covers from 2 MHz to 15 MHz. Frequencies outside these ranges will have less than 360 degrees of phase rotation. NCC-1 Receive Filter Sets must be placed into the proper BAND filter slots corresponding to desired usage. NCC-1 Receive Filter Sets are pairs of filters (2 of the same type), so both NCC-1 receive antenna inputs "A" and "B" exhibit the same pass-band characteristics. Band-pass, high-pass or low-pass filters are available for users to choose and install into their NCC-1 for their desired application. By reducing or excluding frequency-specific interfering noise and signals, the noise floor of the desired pass-band can be lowered for dramatically improved reception. You can install one set or two sets, depending on your desired filtering. NCC-1 "L" and "H" slots may be populated with pairs of band-pass, high-pass, or low-pass filters to suit the specific signal rejection needs of the discerning operator. As an example, an 80 meter DX enthusiast may elect to install two 80 meter band pass NCC-1 Receive Filters, part number DXE-NCCFL-BPF80M, into their NCC-1 "L" BAND slots. This would dedicate their NCC-1 to 80 meter-only operations. Setting the BAND switch to "L" would dramatically reduce noise and signals from outside the 80 meter band, very effectively excluding interference from nearby AM Broadcast, 160 and 40 meter stations. A much lower noise floor on 80 meters could be achieved for dramatically enhanced reception of weak 80 meter DX signals. An additional pair of filters could be installed into the "H" BAND slots, to enhance reception on the higher HF bands. For example, installing 20 meter high pass filters, part number DXE-NCCFL-HP20M, and switching to BAND H would drastically reduce all received noise and signals from frequencies below 13.70 MHz. With advanced planning of additional filter availability, an NCC-1 owner could even swap different filter sets for optimal operations in different contests or band pursuits.

All NCC-1 Receive Filter Sets displayed here are also conveniently listed on a single page in the link tab called "Documentation." Order one or two DX Engineering NCC-1 Receive Filter Sets for your unit and enjoy the best possible performance from your NCC-1.
