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.

InnovAntennas 144 MHz OWL Ultra Yagi Antennas
InnovAntennas 144 MHz OWL Ultra Yagi Antennas offer the 2 meter weak-signal enthusiast undeniable low-noise performance with amazing SWR bandwidth, particularly good gain and an excellent front-to-back ratio. Five Optimized Wideband Low-impedance (OWL) Ultra Yagi antennas are available, starting with six element up through ten element models. InnovAntennas' OWL Ultra Yagi beams have been extensively numerically simulated and optimized using special software that includes a 3D simulation of the boom, the insulators, the connector and the cable; an elaborate numerical simulation of these antennas that was inconceivable a decade before. InnovAntenna has achieved the best of what is technically possible for a wideband 2 meter Yagi. The boom of the 144 MHz OWL Ultra Yagi is 1 in. (25mm) square aluminum featuring through-the-boom insulated elements. The adjustable center fed folded dipole has the side opposite the 50 ohm feedpoint connected to the boom, which removes static charge to protect the transceiver. This antenna acts like a band-pass and noise filter outside the 2 meter band, due to rapidly rising impedance. However, the most important feature of OWL Ultra Yagi antenna is optimization for reduced side lobe in the elevation plane, achieving dramatically reduced received noise, even in high ambient noise city locations. The InnovAntennas OWL Ultra Yagis are suitable for all "weak signal modes" on the low end of the 2 meter band due to the optimization for high gain with incredibly low noise for EME, Meteor Scatter, Tropo-DX, Sporadic-E, etc. Despite the robust construction (the antennas can withstand wind speeds of up to 100 mph (160 km/h), the Yagis are still relatively light and thus suitable for smaller masts or for stacking several antennas. The OWL Ultra Yagis do not include a balun, as the coaxial cable connects directly to the loop driven element dipole. The antenna can handle 5 kW, but the recommended choke balun handles a maximum power of approx. 1.0 to 1.5 kW is possible. Exceptionally good SWR is achieved over a wide frequency range. With excellent gain to noise ratios (G/T ratio), the economical InnovAntennas OWL Ultra Yagis are well suited for use in stacked arrays, for EME, satellite or terrestrial operations. Each model listing describes the key benefits of the OWL Ultra Yagi Antennas. Your antenna is a part of your receiver and arguably the most important part of your station.

As you look through their selections, be aware that advanced, cutting-edge computer modeling and optimization techniques were used to produce EAntenna premier HF beams and state-of-the-art VHF and UHF antennas. Their mechanical designs are very robust in every way, as most are rated for at least 100 MPH wind survival. To see additional information about each antenna, click on the "More Details" link on the antenna of interest. Then click the Specifications tab to see all of the physical and electrical characteristics of that antenna. EAntenna products are offered exclusively in North America by DX Engineering. Plus we can ship internationally! When you are making plans for a new antenna at your station, plan to look right here for the outstanding solutions by EAntenna, "The Best Choice for Your Antenna System!" NOTE: Manuals are normally supplied bilingual. If your manual lacks an English section, contact DX Engineering for an English version. IMPORTANT: EAntenna VHF and UHF Loop Fed Antennas are intended to be mounted horizontally for SSB and CW operation which is at the lower frequency end of the bands, NOT on FM. For example, the 2 meter LFA should be mounted horizontally and is tuned for use on 144-146 MHz and is not intended for FM use on 146-148 MHz. Additionally, the DK7ZB design EAntenna dual-band beams for 2 meters and 70 cm cover only 144-146 MHz and 420-440 MHz, the same European frequency range, and so they are not suitable for FM use in North America. EAntenna Cross Polarized LFA beams have both horizontal and vertical elements with only 144.0 - 144.5 MHz coverage designed specifically for EME or satellite enthusiasts.
