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 OP-DES 50 MHz Yagi Antennas
InnovAntennas OP-DES 50 MHz Yagi Antennas are a relatively new development from InnovAntennas. OP-DES stands for Opposing Phase Driven Element System, in which the ends of the dipole radiator of these antennas is angled backwards towards the reflector, parallel to the boom. This results in opposing phase relationships in the ends of the driven element, providing a very clean directional pattern with few side lobes. The OP-DES Yagi has optimized gain over a wide frequency range, while retaining a good front-to-back ratio. The driven element dipole of an OP-DES antenna has a low impedance of 50 ohms. This eliminates the need for matching elements or a transformer balun. For this reason, the antenna is offered without a balun, but an RF choke balun made of ferrites on coax should be used at the feedpoint terminal studs. With the coaxial cable directly connected to the driven element dipole, well over full legal limit power levels are possible. Like all InnovAntennas Yagis, the OP-DES 50MHz antennas are extremely robustly constructed; the larger model uses truss cables for the boom. All elements of the antenna use high quality aluminum, the clamps and screws are made of stainless steel. The supplied mast clamp is designed for masts up to 2 in. (50mm) diameter. Application Description Monoband Yagis are often used at contest stations, or when you want to use only one band for a certain time, for example to focus on a specific target during sunspot minimum. Another advantage of monoband antennas are the stacking possibilities, i.e. the arrangement of two or more identical antennas properly spaced from each other. InnovAntennas Yagis provide all the necessary technical specifications, so there is no guesswork about the stack spacing. The InnovAntennas OP-DES 50 MHz Yagis are designed through careful numerical optimizations to provide excellent gain with good bandwidth. As a result, a low SWR of 1.1:1 is achieved in the frequency range of 50.0 - 50.6 MHz (6-element) or 50.0 - 51.35 MHz (5-element). The experience of the developer Justin, G0KSC ensure superior operations with these antennas in practice, often supported by a lively exchange between users. TECHNICAL DATA InnovAntennas OP-DES 50 MHz Yagi (Monoband) Antenna Mast Mount: Center Antenna Type Directional Antenna Band 6m Power Handling: 5000 W Polarization: Horizontal Balun Included: No Mast Diameter Max.: 2.00 in.

InnovAntennas LFA-Q 4 Element 50 MHz Loop Quad Beams
InnovAntennas LFA-Q 4 Element 50 MHz Loop Quad Beam from G0KSC represents significant development of LFA Yagis with a substantial difference. The LFA-Q (Loop Fed Array Quad) uses top and bottom booms and through-boom LFA Yagi-style loops arranged vertically for every element. This very rugged design achieves better gain for a given length of boom than standard or LFA Yagi. Also, instead of using symmetrical square or triangular loops, the shape of the loops has been compressed into rectangular form, so the short side sections are exactly 180 degrees out of phase resulting in a cancellation effect, like a balanced line. InnovAntenna LFA-Q achieves great rejection to the sides and the rear of the antenna while retaining excellent gain, f/b and SWR bandwidth across the band. These are amazingly compact, high gain antennas constructed to withstand serious weather conditions! The 50MHz 4 Element LFA-Q is made with tapered elements one-half inch (12.7mm) center sections and 3/8 inch (9.525mm) outer sections. The antenna has fully insulated elements which will ensure continuous, high performance for years to come. The LFA-Q has a twin-boom system, 32mm square with 1.6mm wall thickness. Two boom-to-mast brackets are provided, one on each boom, formed from marine grade stainless steel. Both brackets include 2 square U-bolts for the boom and 2 round U-bolts for the supporting mast. InnovAntennas LFA-Q 4 Element 50 MHz Loop Quad Beam Specs: Gain: 11.26dBi @ 50.150MHz F/B: 29.9dB @ 50.150MHz Peak Gain: 11.3dBi Peak F/B: 30.3dB Power Rating: 5kw+ SWR: Below 1.3:1 from 50.00MHz to 50.400MHz Stacking Distance: 5-8m (7m recommended) 2 Stacked Gain @ 7m spacing: 14.35dBi (free space) 2 Stacked F/B: 27.41dB 2 Stacked Gain @ 5.1m Spacing 15m above ground: 19.25dBi Boom Length: 4m.
