A 5 element 70MHz low-noise LFA Yagi

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 compact 5 element 70Mhz LFA provides stunning performance across the whole 4m band (69.950 - 70.500MHz). Hard to beat with a direct 50 Ohm feed-point and no matching losses!!

Specification

This antenna is made with single piece 3/8 inch (9.525mm) elements with a 1/2 inch (12.7mm) by 3/8 inch (9.525mm) adjustable feed loop section. 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, no guys required.

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.

 

  • Marine grade Stainless Steel Fittings*
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
