InnovAntenna 144MHz 20 Element X-Pol LFA Low Noise High Performance Yagis

InnovAntenna 144MHz 20 Element X-Pol LFA Low Noise Yagis offer excellent performance in the 143.85 to 145.36 MHz This Loop Fed Array Yagi is a full-size beam with 19.02 foot boom, featuring 14.82 dBi of forward gain and a front to back specification of 39.1 dB. Designed by G0KSC, this LFA Yagi is a step forward in the design of yagi antennas, providing an ultra-low noise "front-end" for today's modern 144MHz radios. This rugged 20 element (10 horizontal and 10 vertical) features a 50-ohm feedpoint so there are no matching losses.
The InnovAntennas 20-element X-Pol Yagi is built to withstand harsh weather conditions, with 1.5 x 1.5 in. (40x40mm) square aluminum tubing for the boom and .25 in. (6mm) aluminum tubing for the passive elements; the active elements are .5 in. (13mm) in diameter. Stainless Steel hardware is used throughout the antenna to ensure years of trouble-free service. The boom-to-mast bracket accommodates up to a 2-inch (50mm) mast.
