50MHz 6-Element LFA3 Low Noise Yagi.

InnovAntenna 50MHz 6-Element LFA3 Low-Noise Yagi offers excellent performance across the important 50.0 – 50.5 MHz weak signal section of the 6m band. This Loop Fed Array Yagi is a full size beam with a 22.4 ft. boom, and it offers forward gain of nearly 12dBi and an amazing front-to-back of 29dB. This rugged 6 element LFA3 third generation beam features a bent reflector for more consistent impedance, pattern and performance. The Loop Fed Array has a direct-feed 50-ohm feedpoint with no matching losses.

About this antenna

InnovAntenna 50MHz 6-Element LFA3 Low-Noise Yagi offers excellent performance across the important 50.0 – 50.5 MHz weak signal section of the 6m band. This Loop Fed Array Yagi is a full size beam with a 22.4 ft. boom, and it offers forward gain of nearly 12dBi and an amazing front-to-back of 29dB. This rugged 6 element LFA3 third generation beam features a bent reflector for more consistent impedance, pattern and performance. The Loop Fed Array has a direct-feed 50-ohm feedpoint with no matching losses. G0KSC LFA Yagis are a major step forward in the development of the Yagi Antenna, providing an ultra low-noise "front-end" for any advanced 50 MHz radio. Their well suppressed side lobes in both H and E planes provide excellent side and rear rejection of unwanted signals and noise, making this model ideal for very noisy city locations.

The InnovAntennas 6-element LFA3 Yagi antenna is made to serve in any conditions, with an strong square aluminum tubing boom that is 1.50 in. (38mm) by 0.078 in. (2mm) wall thickness. Tapered elements consist of 0.50 inch (12.7mm) element centers and 0.375 in. (9.5mm) element end sections. 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 for this horizontally polarized 6-element LFA3 Low Noise Yagi antenna.

Also used in production of InnovAntennas LFA Yagis:

Marine Grade Stainless Steel Fittings

Original Stauff Insulation clamps

Mill finished boom and elements for highest levels of accuracy

InnovAntennas are constructed with the best quality materials in order to achieve the best possible mechanical construction, not the cheapest or most profitable. A digital caliper is used to measure the elements during production to ensure parts or within 0.2mm tolerance, ensuring each antenna works as well as the design software model predicts.

A great deal of development time was put into InnovAntennas Yagis, but not only on the advanced electromagnetic design. Extensively modeling on the effect of insulators, booms and other parts ensures that every component of InnovAntenna Yagi has the least effect on performance and pattern degradation.

For the 6-meter enthusiast who wants to beat the noise, enjoy great gain and front-to-back performance, this 6-element LFA3 is ready to serve you well on 50MHz.
