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.

WiMo ERC-Duo USB Interface for Yaesu Rotators
ERC-Duo USB Interface for Yaesu Rotators is a compact interface designed in Germany for connecting compatible Yaesu rotator controllers to a computer via USB. ERC-Duo can connect to all Yaesu rotator controllers that have an 'Ext. Control' connector. ERC-Duo includes a 6-pin mini-DIN cable for the Yaesu DXA series controllers. The ERC-Duo Interface uses the Yaesu rotor control protocol, just like the Yaesu GS-232A/GS-232B interface. This makes this interface compatible with almost all rotor control programs and logging software programs on the market. A key difference and advantage compared to others is the ERC-Duo Interface is powered via the PC USB port, so it is easy to use for either Base or Portable Satellite operations because it does not require an external power supply. Also included is the USB A to USB B cable for the PC connection. Install the USB driver before connecting the ERC-Duo, a simple download from the FTDI website: https://ftdichip.com/drivers/vcp-drivers/. The calibration tool, user manual and control software can be downloaded from the URL provided in the documentation included in the product packaging.

WiMo ATAS 100/120 HF Counterpoise Kits
WiMo ATAS 100/120 HF Counterpoise Kits improve the performance of the ATAS-100 and ATAS-120 antennas when they are used as stationary or portable antennas. The well-known ATAS-100 and ATAS-120 antennas from YAESU were developed as vehicle antennas, but because of their compactness they are often used as portable or stationary antennas. Unfortunately, a balcony railing or the magnetic base alone are typically not sufficient to provide optimal results, so the use of a counterpoise system such as the WiMo ATAS-FGG is useful. The ATAS-FGG counterpoise kit consists of a solid aluminum ring that is attached directly to the ATAS-100 or ATAS-120 antenna with clamping screws and can remain on the ATAS during alternating mobile or stationary use. Eight aluminum radial elements are screwed into the ring and has an overall diameter of 13.12ft. (4m) when fully assembled. If space is not an issue, you can also connect one or more wire radials for the 40m band. NOTE - This counterpoise kit should only be used when stationary and is not intended for mobile use when the vehicle is in motion.

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.

WiMo Phase Lines
WiMo Phase Lines are band-specific phasing cable assemblies, either 2 meter or 70 cm, used on the respective WiMo X-Quad Antennas or other cross-polarized Yagi. They combine the vertical and horizontal elements into either Right-Hand or Left-Hand Circular Polarization, dependent upon beam driven element position. Each cable set comes with two male Type-N connector cables, one for each polarization element, combined into one female Type-N connector for the main 50 ohm coaxial feedline to the station. WiMo Phase Lines are used in non-switchable systems.

WiMo Big Wheel Horizontal Loop Antennas
WiMo Big Wheel Horizontal Loop Antennas are VHF or UHF omni-directional, horizontally polarized antennas used for weak signal work on SSB, CW, and digital modes. They are ideal companions to directional beam antennas; by covering all directions at once, they help make sure you don't miss that rare contact that may otherwise be lost. Constructed from stainless aluminum and stainless steel hardware, featuring low loss Type-N connectors, these unique monoband antennas cover 50 to 52 MHz (1,000 watt) or 144 to 146 MHz (500 watt) or 430 to 440 MHz (200 watt) providing 3 dBd gain. Two Big Wheel antennas vertically stacked will achieve about 5 dBd gain with a monoband power divider or coaxial phasing harness that connects two same-band antennas to one coax feedline.

WiMo Remote Polarization Switches
WiMo Remote Polarization Switches are 4-way mast-mount relays used to change the polarization plane on a WiMo X-Quad or other cross-polarized Yagi. Selectable polarization planes are horizontal, vertical, right-hand circular and left-hand circular. For each band, 2 meters and 70 cm, there are two WiMo Remote Polarization Switches models available, differing by the maximum output power. These remote control polarization switches may be used for WiMo X-Quad Antennas as well as for any third-party cross-polarized Yagi antennas. WiMo Remote Polarization Switches are mast-mountable weather-proof relay boxes equipped with Type-N connectors. Two inputs are for the antenna and one coax output goes to the transceiver. Remote operations require an additional 4-conductor DC control cable, sold separately. Switches are supplied with a mast clamp and the required 4-pin plug for the control cable. The switchbox that would be located at the station is not included. The user may use a simple chassis box or panel and a 4-position rotary switch, or automation control, with an external 12 VDC power supply to switch the relays, which draw 100 mA max. A diagram appears in the instructions (see Documentation). WiMo Remote Polarization Switches were developed in the RF lab of SSB-Electronics and are available only as a WiMo product, exclusively through DX Engineering in North America.
