A Super High Gain 70MHz LFA Yagi optimised for DX applications

The G0KSC LFA Yagi is a major step forward in the development of the Yagi Antenna; it provides a low-noise front-end for your radio so you hear more weak signals. If you suffer with noise or are in a city location, this is the antenna for you. This 11 element 70Mhz LFA provides stunning performance across the whole 4m band (69.950 - 70.700MHz). Hard to beat with a direct 50 Ohm feed-point and no matching losses !!

This is an excellent stacker requiring just 6.5m spacing. See details below.
