A Super Low Noise Yagi for serious DX and EME applications

The G0KSC LFA (Loop Fed Array) Yagi has quickly become 'the one to have' if you are looking for serious weak signal work on VHF and UHF bands. Unlike other companies and designers, G0KSC has dismissed the 'one size fits all' antenna modeling approach and does not model every antenna as if it were for the HF bands. Instead careful consideration is taken to ensure the performance parameters of each antenna fit well with the characteristics of the band in question. Sky and ground noise (temperature) play a role in an antenna's ability to receive signals and the G0KSC LFA Yagi has been modeled for the absolute best noise figures possible, ensuring you can hear anyone that hears you, even if you are QRO and they are not!

The LFA is especially effective for EME where very low noise antennas are required and many hours development have been spent ensuring the highest levels of performance have been achieved in an antenna that is not affected by wet weather conditions. As a single, double and 4 stack (or more) system, the LFA Yagi is the one to have.

Our antennas are constructed with the best quality materials in order the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.1mm of what they should be, this is extremely important on 432MHz and measurements must be as accurate as possible if performance and temperature are to be maintained.

If you are looking for the best of the best from both a performance and mechanical construction perspective then look no further, you have come to the right place!

Specification

This antenna has all parasitic elements made from 1/4 inch aluminium rod. The LFA loop is constructed from 4 pieces of aluminium tube. The sections in-line with the parasitic elements are 1/2 inch while the end sections of the loop are 3/8 inch allowing the user to adjust the loop for best SWR. All elements are fully insulated from the boom, held in place by high quality UV resistant RF neutral insulators which in-turn are held to the boom via stainless steel fixings and fittings.

The boom on this antenna is 1.25 inch square (31.75mm)

If you want an antenna to last and perform in all weathers without SWR or bandwidth shifting, this is it.
