A 5 element Long Boom (2.1m) LFA-Q (Super-rigid Quad-style) Super-Light Quad Style Yagi for 144 – 145MHz
The LFA-Q Packs a bigger punch than a traditional Yagi with MUCH MORE GAIN per metre of boom
If it is GAIN you want from a small boom, this is the antenna for you! Wow, Super compact boom!! Massive 12.2dBi from this antenna!
Another impressive design from G0KSC, ‘The Quad has been InnovAted!’ A Quad-style antenna with full wave length loop elements which provide a number of benefits. First, if the elements are of reasonable thickness (as ours are, they are not wire!) then good bandwidth coverage can be achieved. Next, up to around 7 elements (1.5wl) much better gain per metre of boom can be achieved than would otherwise be possible from a traditional Yagi covering the same bandwidth. Finally, with the dual-boom structure and 1/2” diameter elements, the LFA-Q is extremely rigid and can stand up to some serious weather conditions!
IDEAL PORTABLE OR SOTA USE!
Despite it’s rigidity, the LFA-Q is extremely lightweight and this means even in strong winds, snow and ice the LFA-Q will hold its own.
Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, ensuring they work as well as our software model predicts.
- Marine grade Stainless Steel Fittings
- Original Stauff Insulation clamps
- Mill finished boom and elements for highest levels of accuracy
