11 el 50MHz LFA-BV Yagi (21m)


11 el 50MHz LFA-BV Yagi (21m)

An 11 element  low-noise LFA-BV (designed for and dedicated to K7BV Yagi

The G0KSC LFA Yagi is a major step forward in the development of the Yagi Antenna; it provides a low-noise front-end for your radio so you hear more weak signals. This 11 element 50Mhz LFA provides stunning performance across the important section of the 6mband (50.00 - 50.400MHz). Hard to beat with a direct 50 Ohm feed-point and no matching losses and suppression of unwanted noise !! This is an excellent antenna for EME see the many reviews around the Internet!

This antenna has very highly suppressed lobes in both azimuth and elevation plots and therefore is idea for very noisy city locations. If you want to beat the noise in a mid-sized 6m Antenna, this is the one for you!

Specification

This antenna is made with tapered elements 5/8 inch (15.88mm) centers and 1/2 inch (12.7mm) outer sections. 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 3 inch square (76.2mm) 10SWG aluminum (3.2mm wall). A comprehensive (6 guy) boom guy system is provided with this antenna, Kevlar rope and stainless steel fixtures, fittings and turnbuckles.

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 (with an accuracy of.01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, this ensures they work as well as our software model predicts.

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 or our antennas have least effect on performance and pattern degradation.

  • Marine grade Stainless Steel Fittings
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
