DX Engineering NCC-2 Receive Antenna Phasing Systems
Imagine adjusting the controls to knock out strong interfering stations or noise—and then being able to copy and log that weak DX station. By successfully combining the right antennas with the advanced phasing capabilities of the NCC-2, this is the operating thrill that every radio enthusiast can enjoy, again and again! DX Engineering NCC-2 Receive Antenna Phasing Systems are variable phasing controllers that combine the 300 kHz- 30MHz received signals from one transmit antenna and one receive antenna, or from two dedicated receive antennas. Combining signals from two stationary antennas physically spaced 1/10 to 1/2 wavelength apart creates an array pattern with signal peaks and dips called nulls. Adjusting the NCC-2 Phase and Balance controls have the effect of electronically rotating or steering that pattern. Steering the null direction to significantly weaken a local or distant interfering signal or noise is known as "Noise Cancelling." This "Noise Cancelling Controller" (NCC-2) can dramatically enhance the reception of weak signals from non-null directions. This "reverse-beam" capability on radio frequencies AM Broadcast through HF can provide amazing benefits for many types of AM DX and SWL receiving and ham radio operating. Work new DX, hear the weak station in casual regional conversations, snag the rare multiplier in contests and hear beyond the noise and interference in dire circumstances. DX Engineering NCC-2 Phasing Systems now feature the built-in RTR Receive-Transmit Interface relay system that expands the exciting benefits of antenna phasing for interference reduction in two ways: * First, the NCC-2 can combine signals from the HF transmit antenna and a separate receive antenna to effectively notch-out strong stations or noise. Almost any Amateur can now enjoy the benefits of antenna phasing and noise-nulling, even those with space limitations for separating the receiving and transmitting antennas. * Second, the user of any standard HF transceiver that lacks a separate receive antenna input can have enhanced reception of noise and signal nulling with the DXE-NCC-2 and two antennas. Rear panel SO-239, F and BNC connectors make the NCC-2 extremely versatile and easy to connect to almost any receiver or HF transceiver up to 200 watts. Redesigned with plug-in modular circuit board sockets, the NCC-2 includes one switched and powered internal slot and two passive internal slots per channel to accommodate these new options: * DXE-RPA-2-PM Receive Preamplifier Plug-In Modules (powered): one per channel for low-signal passive antennas with poor ground conditions * DXE-RG5000HD-PM Receiver Guard 5000HD Plug-In Module (passive): Front-end protection for the NCC-2 and the receiver * DXE-IT-PM 75 to 50 ohm Impedance Transformer Plug-In Module (passive): to match 75 ohm RX ANT feedlines to NCC-2 50 ohm internal impedance * NCC-2 Receive Filter Sets (passive, non-switchable): High Pass, Band Pass and Low Pass Filters for 160, 80, 40 meters typically in stock, with other band filters available individually by special order. DX Engineering NCC-2 Receive Antenna Phasing Systems offer these new additional benefits: * Multi-Color Status Indicating LEDs for Power, RTR Mode and Preamp Power CH A and CH B * New Radio Key Line Input with RX Enable Output-RTR Failsafe to prevent RF damage to NCC-2 and RX equipment * New ACC Key Line Output RCA female 'ground on transmit' pass-through for Amplifier or Accessory * New screw-on 2.1mm DC connector to prevent accidental power cable pull-out * Operates on +13.8VDC @ 2A input to power the NCC-2 and internally jumper set Bias Tee on each RX ANT ports for coax fed Active Verticals and other accessories.

WiMo QRM Eliminator
The WiMo QRM Eliminator is a simple signal phasing device that can effectively reduce or remove noise interference for dramatically improved reception from 3.5 to 60 MHz. The QRM Eliminator is based on a totally innovative concept and cannot be compared to the performance of noise blanker or DSP circuits. Removing the noise before it gets to the receiver is the superior method of interference reduction. With the WiMo QRM Eliminator you can get rid of local interference almost entirely, up to an S9 level, with the likely result of completely clear reception! You don't have to understand the cause or type of interference nor do you need to know the location of its source. It doesn't matter if the interference originates from your own station or from a welding unit hundreds of feet away. The QRM Eliminator simply connects to the antenna port of transceiver and to the antenna (or amplifier input), without any radio modifications required. An additional user supplied auxiliary receiving antenna is required, such as a properly positioned 8 ft. outdoor dipole antenna or a simple 20 ft. wire in the shack, for example. This "noise sense" antenna receives mostly unwanted signal, while the transmitting antenna receives the same interference in a different phase along with the desired signal. The QRM Eliminator allows the adjustment of the amplification and phase to cancel out the unwanted signal before it reaches the receiver front end! Noise or interference nulling can provide over 45 dB of unwanted signal suppression, in many cases resulting in clear reception of the desired signal. The QRM Eliminator is built into a shielded metal enclosure, functions over the frequency range of 3.5 through 60 MHz, and has a status LED to indicate when the unit is turned on for phasing. The unit has a built-in T/R relay with PTT control via a rear panel RCA phono connector for the transceiver amplifier keying line. The QRM Eliminator automatically switches the Main antenna connection to the transceiver during transmit. Also, simply turn the unit off to bypass the phasing unit for normal reception on the Main transmit antenna. Click "More Detail" below to see additional information about this exciting device. You may not believe the power of interference phase nulling until you have experienced it for yourself. Order the WiMo QRM Eliminator exclusively in North America from DX Engineering.

The maximum transmit power is 5 kW with SWR less than 1.1:1 in the range 50-50.45 MHz with average gain of 12.9 dBi. This antenna was specially designed for G3WOS, who was looking for a perfect antenna for 6m for his free standing mast. The relatively long boom provides good gain with excellent front/rear ratio, so this antenna is great for EME and "weak signal" DX. This antenna has very highly suppressed lobes in both azimuth and elevation plots and therefore is ideal for very noisy city locations. If you want to beat the noise in a mid-sized 6m antenna, this is the one for you! The G0KSC LFA Yagi is a major step forward in the development of the Yagi Antenna; it provides a low-noise front-end for your radio so you hear more weak signals. This 7 element 50 MHz LFA2 is another exciting slant on the LFA design with both the last third of both the reflector and first director elements being bent towards the driver loop in order to enhance performance. Incredible levels of F/B have been achieved providing the ultimate in rear-end suppression. This antenna is made with tapered elements 16mm center and 13mm outer sections. The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which accommodate 2 inch (50mm) masts. Boom is 2 inch (50mm) aluminum in the center, tapering to 40mm with a 45mm section, all with 2mm booms. A boom guy system is provided with this antenna. Marine grade Stainless Steel Fittings Original Stauff Insulation clamps Mill finished boom and elements for highest levels of accuracy Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the components of our antennas have least effect on performance and pattern degradation.

InnovAntennas 10M or 11M LFA-Q Loop-Fed Quad Beams
InnovAntennas 10M or 11M LFA-Q Loop-Fed Quad Beams from G0KSC represents significant development of LFA Yagis with a substantial difference: LFA-Q (Loop Fed Array Quad) Beams use top and bottom booms with through-boom LFA Yagi-style loops arranged vertically for every element. This very rugged design achieves better gain for a given length of boom and much lower noise for better signal quality compared to conventional Yagi antennas. InnovAntenna LFA-Q quad structure provides high directivity, eliminating unwanted spurious radiation. They achieve great side and rear rejection while retaining excellent gain, front-to-back and SWR bandwidth across the band. These are amazingly compact, high gain directional antennas, constructed to withstand serious weather conditions! Antennas of this series can be built and tuned to operate on a 500 kHz section of the 10 meter 28 MHz Amateur Band or on the 11 meter 27 MHz Citizens Band. The desired band is easily selected by changing the length of the outer element sections during construction – exact dimensions are provided in the instructions. The driven loop element feedpoint impedance is 50 ohms which allows a direct feed at high transmitting power. Vertical stacking of two or more antennas can significantly increase directivity, gain and signal quality; an interesting alternative when available space prevents the installation of long boom beam antennas. Just like other HF quads, LFA-Q vertical loop-fed quads are inherently quieter than a Yagi of the same size, making them a perfect choice for use in any location with high ambient noise level, such as a city or densely populated neighborhood. There is a 10M or 11M LFA-Q Loop-Fed Quad Beam version that matches your space, support, and wallet: - The 2-element economy version has loop spacing booms of only 2.3 ft. (70 cm); - The 3-element compact version booms are 10.5 ft. (3.2m) in length: - The 4-element performance model boom lengths are 26.9 ft. (8.2 m). Each LFA-Q is very stable mechanically, with mast clamps on each boom, top and bottom! Thanks to the use of high-quality materials, extensive modeling and testing, the durability and reliable performance of InnovAntennas 10M or 11M Loop-Fed Quad Beams is undeniable.

DX Engineering NOISELOOP Portable Receive Flag Antenna Kit
DX Engineering NOISELOOP Portable Receive Flag Antenna Kit is based on the design by Don Kirk, WD8DSB. Don's article on this antenna is published in the March 2021 issue of QST Magazine (used by permission). The DXE-NOISELOOP is a kit of parts to build this receive-only portable directional HF loop antenna, which measures only 48 by 24 inches plus 36 inches of mast-handle. It may be used while walking or stationary with your portable HF receiver. Oriented vertically, this loop antenna features a cardioid pattern at the horizon with a deep null of up to 30 dB rejection. It is an excellent tool for locating noise sources from 1.8 through 30 MHz and for low-noise, general coverage reception from the AM broadcast band through 30 MHz. An optional Preamplifier-Attenuator Unit, DXE-NL-PRE-ATT-1, may be attached to the loop mast handle for enhanced operations. An IC-705, a portable SW or a handheld HF receiver are excellent choices for searching for local noise sources with the NOISELOOP, around the neighborhood and even around your own home. This Portable Flag Antenna Kit includes everything needed to make the antenna: fiberglass tubing for the frame and handle, mounting plate, separate PC boards for the bifilar wound transformer and load resistor, antenna wire, coaxial cable with male BNC and stainless steel hardware. Simple hand tools and a solder iron are required for assembly. Included instructions detail assembly. This kit will typically take between 1 and 2 hours to build. The WD8DSB Portable Flag Antenna design has become a real game changer in direction finding of RFI on MF and HF frequencies, and you will also find it an invaluable tool when hunting RFI due to the following key features. *Unidirectional (unlike a tuned loop) *Broadband (unlike a tuned loop, excellent for AM DXing, SWL and Amateur) *Portable (easy to walk with while directional noise finding or HF Fox Hunting) Traditionally Flag antennas are large and designed for stationary use, but the idea for this antenna was to design a Portable Flag. It was designed to be the largest possible (to maximize gain) that would fit inside a car and it's still small enough to maintain a cardioid pattern up through 30 MHz. The portable Flag has an approximate dimension of 2 feet tall by 4 feet long which you (or a helper) can easily walk with while tracking down a signal. Unlike a tuned loop, the Portable Flag is a broadband antenna with unidirectional properties, and it's designed for direction finding from 1.8 to 30 MHz as long as an appropriate preamp is used. It's even useful for direction finding down in the AM broadcast band. The rear of the antenna produces a sharp null when pointed at the signal of interest and the sharp null is often used for direction finding versus using the broad peak which occurs when the front of the antenna is pointed at the signal of interest.

DX Engineering Receiver Guard Electronic RF Limiters
DX Engineering Receiver Guard RG5000HD Electronic RF Limiters are the best choice of inline devices to protect your receiver antenna inputs. The Receiver Guard is a receive antenna input limiter specifically designed to protect a sensitive receiver front-end against high levels of RF and potential damage. At the heart of each Receiver Guard is a highly effective electronic RF limiter covering 500 kHz to 150 MHz with an insertion loss under 0.15 dB up to 50 MHz and under 0.30 dB up to 150 MHz. The multi-stage design includes a gas discharge tube for maximum pulse energy protection. The DXE-RG5000HD rejects 10 watts of catastrophic receive antenna feedline RF while passing a maximum signal of about 87 dB over S-9, which is only 25 mw, a signal level that is well below the point of front end damage. Receiver Guards are a must for multiple radio contesting stations and they provide low-cost front-end "insurance." Use them in these common high-RF situations: - Receive antennas in very close proximity to transmit antennas - Field-day operations with many transmitters in close range - Multi-transmitter contesting sites - Neighboring Amateur and CB operators - Frequent high-power mobile encounters Extensively tested and proven in real-world stations, the Receiver Guard works for all radios and offers the ultimate performance required by the upper tier of transceivers tested to have the best narrow-spaced third-order dynamic range or published RMDR (Reciprocal Mixing Dynamic Range). These are passive electronic limiters, so competitive contesting stations use separate band filters in addition to the Receiver Guard. When there are high levels of RF on your receive antennas, the DX Engineering Receiver Guard generates far less harmonic noise than other limiters on the market, which allows your station to continue to operate safely and competitively. At normal HF signal levels the RG5000HD operates continuously with no effect on the performance of your station while providing the best possible protection for your radio. Here are key Receiver Guard features: * Keeps stray high levels of RF from damaging your receiver input * Ideal for separate 160 and/or 80 meter receive systems with large pulse and RF energy capture area * Uses state of the art components for maximum protection of receivers * Under 6 ns response time * Multi-Stage protection * Very low insertion loss * Uses BNC type connectors to avoid accidental connection to a transmit feedline * Has been developed and tested in world-recognized multi-multi contest station K3LR Specifications - DX Engineering Receiver Guard model DXE-RG-5000HD - Frequency Range: 0.5 through 150 MHz - Insertion Loss: < 0.15 dB up to 50 MHz, < 0.3 dB 50 MHz up to 150 MHz - VSWR: < 1.2:1 - Maximum Output Level at 10 W input: +14 dBm (0.025 W) - Maximum Power Handling: 10 W CCS (Continuous Commercial Service) - Device Impedance: 50 to 75 ohms, unbalanced - Connectors, Input and Output: BNC female Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.

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.

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.
