2/2 (4) element 10/18MHz Yagi (2.5m) Force12

A super-compact dualband 10/18MHz WARC band Yagi with single feedpoint

The 4-LFAR-30/17, an Excellent super-compact Dual band LFA-R Yagi for the 30m & 17m bands
A super-compact dualband 10/18MHz WARC band Yagi with single feedpoint

The LFA-R is one of the latest designs from the desk of G0KSC. The LFA-R uses no reflector, just a dipole/LFA hybrid driver laid flat on the boom with one close proximity director. The dual band version has the second band drive element placed close enough for 'open-sleeve' coupling to occur in order service can be provided on a second band. This antenna does not give wide band performance (and thus is suited to the WARC bands) but does give incredible levels of gain and F/B permetre of boom. take a look at the specifications below, we think you will agree this is an awesome performer for such a short antenna!

 This antenna deploys elements tapering from 1.5 inch (31.7mm)  to 3/8 inch (9.525mm) for 10MHz with elements starting at 1 inch (25.4mm)  tapering through 3/8 inch (9.525mm) for 18MHz . The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts.  Boom is 1.75 inch square 10SWG aluminum.

Our antennas are constructed with the best quality materials in order the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used to measure the elements during production to help ensure the best possible results when installed.

Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make-up of our antennas has least effect on performance and pattern degradation. More information can be found here

  • Marine grade stainless steel fittings
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
  • Specifications subject to change without notice
