This is a ten-element LFA (Loop Fed Array) that provides excellent gain and impressive suppression of side and rear lobes in both the E- and H-plane. This beam operates in the 430-440 MHz range, for SSB/CW/Data modes. It's an excellent building block for a phased array for Moonbounce and other weak-signal work. This beam requires a balun or common-mode choke at the feedpoint. The feedpoint is split, with no connector.
The LFA (Loop Fed Array) Low-Noise Yagi is very different from the traditional dipole fed Yagi in many ways with its primary benefit being unwanted noise rejection. The LFA has a rectangular shaped, full wave loop driven element that is laid flat on the boom between and in-line with the parasitic elements . Then there is the way in which the loop functions.
The smaller end sections which run parallel to the boom, are engineered to be 180 degrees out-of-phase with each other. This provides the same effect as is seen within ladder-line feeder; each side cancels the other out and therefore, minimum radiation occurs. In practice this translates to highly suppressed side lobes and side-on signal rejection.
This feature also plays a role in reducing F/B (Front to Back ratio), F/R (Front to Rear ratio) and broad-banding of the antenna too. It is these attributes which help give the LFA class-leading all-round performance at almost any boom length and for any given band.
We aim to dispatch all parcels within 24hrs. We are normally able to dispatch parcels SAME DAY where orders are received before 2.00pm Monday to Friday.
 
Whilst we try our best to ship same day, we cannot guarantee delivery time. You will however receive tracking details as soon as your order has been processed.
 
Please note that we do not process orders over the weekend, so orders placed after 2pm on Friday will not ship until Monday.
 
Please allow an extra processing day for international orders to enable us to complete export/import custom clearance declarations.
