Technical description 18485.0043
The LFA-Q Yagis from G0KSC represent a significant further development of the Yagi antennas. Due to the loop-shaped elements, there are considerably fewer side lobes in the directivity pattern. This means less energy is absorbed from the sides or rear, and the antennas are designed for the best gain with a relatively short boom. The SWR in the range 50-50.4 MHz is less than 1.4:1, the gain is approx. 11.3 dBi.
Application description 18485.0043
The LFA-Q (Loop Fed Array Quad) Low-Noise Yagis are a further development of the LFA Yagis with one difference. Instead of using symmetrical square or triangular loops, the LFA-Q uses LFA Yagi-style loops to achieve a high level of side rejection. This with every element and not just the spotlight.
The shape of the loops has been chosen so that the short side sections are exactly 180 degrees out of phase and therefore a cancellation effect occurs, similar to a symmetrical feeder line. This means that a high level of suppression can be achieved both to the sides and to the rear of the antenna.
