Technical description

LFA Yagis differ significantly from traditional Yagi designs.


The LFA ("Loop Fed Array") has a rectangular dipole with 1λ length. The dipole lies flat on the boom in the same plane as the parasitic elements. The outer sides of the dipole are parallel to the boom and are designed to be exactly in phase opposition (±180°).


This causes signals on these sides to cancel each other out, resulting in significantly reduced side lobes, low G/T values, and a better front-to-back ratio.


This concept can be applied to almost any boom length.


LFA Yagis have 50Ω impedance and do not need any lossy transformations.

Application description

We offer the 144LFA Yagi antennas in different variants. So you can choose the right antenna for your specific application.


  • LFA5 with 5 elements and 1.82 m short boom for small space requirements


  • LFA7 with 7 elements and still manageable boom length of 2.95 m


  • LFA8 with 8 elements and a boom length of 3.77 m


  • LFA9 with 9 elements at a boom length of 4.50 m and a full gain of almost 20 dBi above ground (e.g. at 10 m height). A guy wire is not yet needed


  • LFA11 with an already quite stately 6.5 m boom and 11 elements. The required material for bracing the boom is included in the delivery.


  • LFA13 with 13 elements and a guyed boom of 7.90 m length


  • LFA16 with a mighty 10.92 m long guyed boom and 16 elements
