The new LFA-R reflector-less Yagi is a step forward in Yagi design and performance. Excellent levels of gain per foot of boom from this compact super-performer
The new 6R6-HD from InnovAntennas Exclusive
The new LFA-R is a new, reflector-less Yagi from the design table of G0KSC. The LFA-R provides excellent performance in terms of both forward gain and F/B too and covers the important bottom end of the 50MHz band with ease.
The 6R6 sits on a 6.5m (21') boom yet punches with a very respectable 12.1dBi gain while still delivering well over 21dB F/B (front to back) ratio.

Note: 2 rather that 4 square U-Bolts (boom securing) are used on production models and is more than sufficient.

This antenna is made with a 5/8 inch (15.88mm) and 1/2 inch (12.7mm) diameter tube LFA loop which has 3/8 inch (9.525mm) loop ends with a wall thickness of 1.6mm. Parasitic elements are tapered, 5/8'' to 1/2'' tube ensuring high performance for many years to come. Boom is 1.5inch. This antenna is not made cheaply, it is made to perform and to do so for many years.
No figures are made up here as they are in some Ham Radio adverts, all performance figures are verified in the very latest software simulation packages with some antennas being professionally confirmed on an antenna range.
