InnovAntennas DXR Series Multi-Band HF Beams
InnovAntennas DXR Series Multi-Band HF Beams have short booms with full-size elements or capacity-loaded shortened elements, all with excellent performance, making them very popular internationally. The DXR Series interlaced-element antennas, optimized by G0KSC over a long period of time, achieve the best possible balance between compact size and performance. For the DXR Series Multi-band Yagis, equal attention was paid to a very solid construction and sufficiently small component and packaging size, to keep shipping costs within reasonable limits. Click on any model listed for specific details and specifications. InnovAntennas DXR Series Multi-Band HF Beams are available exclusively from DX Engineering in North America. Important features of InnovAntennas DXR Series Multi-Band HF Beams: * No traps, matching links, or hairpins * Only one feed line for all bands * Careful selection of materials without regard to cost * Very robust construction with still manageable package size The DXR Series beams use a 1.97 x 1.97 in. (50 x 50 mm) square boom with 0.078 in. (2 mm) wall thickness. A square boom has the advantage that the elements cannot twist in the plane. On the other hand, it is slightly heavier than a round boom of the same stiffness. The DXR Yagis do not require any bracing of the boom. The longest elements are 1.378 in. (35 mm) diameter in the middle and taper relatively quickly to achieve a good compromise between weight and strength. This construction also helps to avoid constant vibration even in light winds. With these multi-band Yagis, care has been taken to ensure that there are never more than the elements of three bands nested within each other. This is because each additional element for one band can cause interference on another band. This negative effect was avoided by careful manual optimization. The result is the best possible matching over a wider band range than other antenna designs. In most cases, no tuner is necessary; the SWR minimum can be precisely set by adjusting the element lengths. Due to the robust construction and the absence of moving or electrically active components such as coils, traps, hairpins, etc., an InnovAntennas DXR beam is maintenance-free for many years. The insulators are UV-resistant and designed for a wide temperature range. The mounting hardware uses sea-water resistant stainless steel and the aluminum is type T6 6066/6082, which is also used in aviation. It is nice not to have to climb the mast every year to maintain the antenna. The DXR Series Multiband beams are designed to require only one feed line. This makes installation on a mast with a rotor very easy. And the use of modern SDR transceivers, which allow the observation of several bands at the same time, becomes really useful. The one feed line is connected directly to the solid distribution rails of the fed elements. By avoiding baluns, matching elements, traps, or hairpins for tuning, transmit power is only limited by the coaxial cable and connectors. Note: Front-to-back ratio (F/B) and SWR bandwidth data for the DXR Series will be added as it becomes available. Many models of the DXR Series are available as a "super-compact" version, on which the longest elements have been shortened with capacity hats, thus reducing their turning radius considerably. The installation of these impressive antennas is possible even where space is limited.

InnovAntennas DXE12-6 Heavy Duty HF+6M Yagi
InnovAntennas "DXE Twelve-Six" is a heavy-duty 12 element multi-band HF plus Yagi that covers the 20, 17, 15, 12, 10 and 6 meter bands with a single coax connection to match modern HF+6m transceivers. Excellent performance on each band is achieved by direct feed and no traps, coils or hairpins for class-leading radiating efficiency. This ruggedly built beam antenna is ready for harsh weather environments with aerospace grade T6 6066/6082 aluminum tubing, UV and temperature protected insulators and all stainless steel hardware. The stout, modest length 17.5 ft. (5.33m) boom is made of 2 inch (50mm) square tubing and perfectly interleaved rigid fast-taper elements easily shed the wind. Choose this HF beam for long-term reliability and power handling that exceeds most coax specs. With low SWR across all six bands, 20 through 6 meters, InnovAntennas DXE 12-6 is a great value that packs a punch.

InnovAntennas 50MHz 9-Element LFA-KW Yagi
InnovAntenna 50MHz 9-Element LFA-KW HD Yagi is a giant. This 49 ft. long boom, low noise Loop Fed Array model achieves the Lowest Ever Noise Figure! The G0KSC LFA Yagi is a major step forward in the development of the Yagi Antenna, providing a low noise "front-end" for any advanced 50 MHz radio to easily hear weak signals. This amazing 9 element LFA provides stunning performance across the 50.0 – 50.4 MHz weak signal section of the 6m band. This antenna is hard to beat with a direct-feed 50 Ohm feedpoint, no matching losses and suppression of unwanted noise. EME reviews on the Internet confirm that this 9 element LFA is an excellent antenna. It's very highly suppressed side lobes in both H and E planes make this model ideal for very noisy city locations. For the 6 meter enthusiast who wants to beat the noise AND enjoy maximum gain and front-to-back performance, THIS is the 50 MHz Yagi for you.
