5 element 50MHz LFA-3-HG Yagi (3.9m) 2017
A 5 element low-noise LFA-3 compact Yagi - The LFA3 is the thrid generation of G0KSC design LFA's new for 2017!
The G0KSC LFA-3 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. This compact 5 element 50Mhz LFA-3 provides stunning performance across the important section of the 6m band (50.00 - 50.300MHz). Hard to beat with a direct 50 Ohm feed-point and no matching losses and suppression of unwanted noise!!
Note: The HG LFA3 has been optimised to provide class-leading gain for its given boom length.

This antenna is made with single piece (centre join at insulator) 5/8 inch (15.88mm) elements with 1/2 inch (12.7mm) tips with loop ends being 3/8'' (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. Boom is 1.25 inch square 16SWG aluminum.
Our antennas are constructed with the best quality materials in order that 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 0.2mm of what they should be, this ensures they work as well as our software model predicts.
Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up of our antennas have least effect on performance and pattern degradation. More information can be found here
