18485.0036 · LFA

50MHz 3-Element Low Noise LFA Yagi .

The LFA Yagis from G0KSC represent a significant advancement in Yagi antenna design. The loop-shaped, phase-fed dipole results in considerably fewer side lobes in the radiation pattern. This means less energy is absorbed from the sides or rear, making the antenna more stable and achieving higher gain in the main direction.

About this antenna

  • 50-LFA-3: Very compact 3-element Yagi with a low-noise LFA dipole; thanks to its short 2.14 m boom, it is well-suited for use even in challenging space conditions. The gain is 8.92 dBi, and a value of 11.26 dBi is possible when stacking two antennas vertically.
