InnovAntennas 50MHz 7-Element LFA-HD Low Noise High Performance Yagi
InnovAntenna 50MHz 7-Element LFA-HD Low Noise Yagi offers amazing performance for its price for the critical 50.0 – 50.4 MHz weak signal section of the 6m band. This "Loop Fed Array" Yagi is a full size beam with a 29.2 ft. boom length and it offers great forward gain of 12.8dB and an incredible front-to-back specification of 43.3dB! This rugged LFA-2 second generation 7 element beam features a direct-feed 50-ohm feedpoint, no matching losses and excellent rejection of unwanted signals and noise. It's well suppressed side lobes in both H and E planes make this model ideal for very noisy city locations. The InnovAntennas 7-element LFA-HD Heavy Duty Yagi antenna is truly made to survive harsh weather conditions, with a rugged square aluminum tubing boom that is 2 in. (50mm) at the center, tapering to 1.77 in. (45mm) and 1.58 in. (40mm) at the ends, with each section a 0.078 in. (2mm) wall thickness. Tapered elements consist of oversized 0.63 inch (16mm) element centers and 0.51-inch (13mm) element end sections, both with 0.078 in. (2mm) wall thickness, the same as the boom. Fully insulated elements ensures continuous, high performance in all weather conditions for many years to come. The boom-to-mast bracket accommodates up to a 2-inch (50mm) mast and a Kevlar single-line truss support system is provided with this horizontal polarized 7-element LFA-HD Yagi antenna. A capable and accurate tower-mounted rotator is required. For the 6-meter enthusiast who wants to beat the noise, enjoy great gain and incredible front-to-back performance, all for a great price, THIS 7-element LFA-HD is one of the most exciting 50MHz Yagis on the market!

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. Weight: 6Kg / 13LB Turning Radius: 2.02m / 6.66ft Wind Loading: 0.22 Square Meters / 2.36 Square feet. Wind Survival: 160KPH/100MPH.
