2 element 28MHz LFA-Q Quad Beam (0.7m)

A 2 element  28-29MHz (600Khz sections) LFA-Q Quad-style beam antenna -  Second Generation LFA Yagi !

The G0KSC LFA-Q beam antenna provides a new slant on the proven quad style beam antenna. The LFA-Q is a super-strong, super-rigid Quad which provides very high levels of gain for it's size, while at the same time maximising all round performance.  Hard to beat with a direct 50 Ohm feedpoint and no matching losses and suppression of unwanted noise due to the closed loop system.

The LFA-Q deploys 2 x 1.25'' square booms one at the top of the structure and one at the bottom which enable the antenna to be ultra-rigid and stand up to extreme weather conditions such as severe ice and wind loading.

This 2 element LFA-Q is an excellent option if you do not have space, especially stacked !! 2 at just 7m spacing provides 15.23dBi (when placed 10m above ground)!!

NOTE: With all our HF antennas we can custom design your element taper and element size requirements in order to cater for all weather and installation requirements.

Customer comment on the LFA-Q:

''Very nice...assembled and installed over the last two days - even though it arrived over night!

Performs extremely well - It replaced a MET 144 8T
