A 3 element 27-28MHz (500Khz sections) LFA-Q Quad-style beam antenna handles 20KW+ !. 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 is one of the only 11m antennas on the market that will handle 20KW+ out of the box. If you want to run an antenna that can take power that had excellent gain, look no further than the LFA-Q!
The LFA-Q deploys 2 x 1.5'' 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 3 element LFA-Q is an excellent option if you do not have space, especially stacked !! 2 at just 8m spacing provides 16.6dBi (when placed 10m above ground)!!
