INNOV 4 Element 70mhz LFA Yagi

4 element high-gain LFA Yagi

This compact 4 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!

Due to the 4m band being fairly low in activity, it has been designed with reduced F/B and maximum gain while still holding an incredible SWR curve throughout. With gain in mind, thicker 1/2inch elements have been used on this particular model too. It will prove popular with a very short boom and almost 10dBi forward gain.

It is made with single piece (2 piece outside of UK) 1/2inch elements with 3/8inch diameter loop end sections. The antenna has fully insulated elements which will ensure continuous high performance. Boom to mast brackets are included with the antennas which will support 2 inch masts. Boom is 1.25inch square 16SWG

The antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production.
