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.

InnovAntennas LFA3-HG 50 MHz 5-Element Yagi
InnovAntennas 50 MHz LFA3-HG 5-Element Yagi was designed to have the best gain on a relatively short boom. This antenna offers forward gain of 10.7 dBi (16.2 dBi at 10m above ground) and an exceptional 31 dB front-to-back rating with SWR less than 1.4:1 in the 50-50.4 MHz range. The low profile LFA3 dipole achieves a significant reduction of noise, allowing clear reception of much weaker signals, a key component of operational improvements and success. The LFA3-HG has a 12.8 ft. boom and a low 2 sq. ft. wind load, making this beam ideal for typical 6 meter stations as well as for stacking to maximize gain, especially when available space restricts the use of a longer boom Yagi. It features a 1.25 in. (32mm) 16-guage square aluminum tubing boom for rugged reliability and low weight. This antenna is made with single piece 5/8 inch (15.88mm) element centers, 1/2 inch (12.7mm) tips with loop ends made with 3/8 inch (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. The introduction of the loop-shaped and phase-fed dipole achieves considerably fewer side lobes in the Yagi directional pattern. With less energy absorbed from the sides and from behind, these antennas becomes quieter and they achieve a higher forward gain. The 50 MHz Monoband LFA Yagis from G0KSC represent a significant advancement in the development of Yagi antennas.

InnovAntennas VertiGO HF Vertical Antennas
InnovAntennas VertiGO HF Vertical Antennas cover multiple bands when fed as a non-resonant radiator using a remote antenna tuner mounted at the base. They can also be fed directly as a monoband vertical and are typically and most easily installed as a ground-mounted vertical, depending on the location and the support. To achieve the matching required by modern transceivers and amplifiers, other shortened vertical radiators use traps or coils but, those components contribute to losses; power lost as heat. InnovAntennas VertiGO Antennas radiate on all bands along their entire length. Radials are required for efficient operation of any HF vertical; 16 or more ground radials are better, where their length isn't critical. A remote tuner installed at the base of the antenna provides maximum efficiency and the best performance on the bands indicated. Higher frequencies will tune but higher angle patterns will limit performance. A ferrite bead choke should be used at the remote tuner on the coaxial cable from the station to prevent it from radiating and collecting RF noise. VertiGO Vertical Antennas from InnovAntennas are available in three different height versions, each with rugged aluminum tubing sections, swaged and slit at the top for the element clamps. Brackets and clamps are included for mounting to a user supplied support pipe.
