Technical description

Yagis with LFA dipole ('Loop Fed Array') differ significantly from traditional yagi designs.

The LFA antenna 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 run 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 require lossy transformations.

The EAntenna LFA antennas are constructed with square aluminium booms (40 x 40, 50 x 50 or 70 x 70 mm) to prevent twisting of the elements. The elements consist of stepped aluminium tubes with 30 to 12mm diameter. The mast plate is included in the delivery.

Application description

LFA yagis offer an excellent gain-to-length ratio for monoband yagis, and have few side lobes. This reduces the noise of the antennas, so it makes sense to use them in urban environments with a lot of 'man made noise'.

The robust construction is designed so that these antennas can also be used in strong winds, for example on the coast. Due to the clean directional pattern, the LFA Yagis are also well suited for interconnecting several antennas to achieve more gain or to cover several target regions at the same time.
