InnovAntennas LFA-Q 4 Element 50 MHz Loop Quad Beams

InnovAntennas LFA-Q 4 Element 50 MHz Loop Quad Beam from G0KSC represents significant development of LFA Yagis with a substantial difference. The LFA-Q (Loop Fed Array Quad) uses top and bottom booms and through-boom LFA Yagi-style loops arranged vertically for every element. This very rugged design achieves better gain for a given length of boom than standard or LFA Yagi. Also, instead of using symmetrical square or triangular loops, the shape of the loops has been compressed into rectangular form, so the short side sections are exactly 180 degrees out of phase resulting in a cancellation effect, like a balanced line. InnovAntenna LFA-Q achieves great rejection to the sides and the rear of the antenna while retaining excellent gain, f/b and SWR bandwidth across the band. These are amazingly compact, high gain antennas constructed to withstand serious weather conditions!

The 50MHz 4 Element LFA-Q is made with tapered elements one-half inch (12.7mm) center sections and 3/8 inch (9.525mm) outer sections. The antenna has fully insulated elements which will ensure continuous, high performance for years to come. The LFA-Q has a twin-boom system, 32mm square with 1.6mm wall thickness. Two boom-to-mast brackets are provided, one on each boom, formed from marine grade stainless steel. Both brackets include 2 square U-bolts for the boom and 2 round U-bolts for the supporting mast.
