Hello Justin, how are you ?

I wish to send you some picture of nice 11 EL LFA and a screenshot of VNA with Return Loss - SWR and Smith chart...

The RL is well down to 36 dB @ 144300. Sometimes was 37 dB.

The antenna was at 7/8 meter on the ground, with little choke of H200 low loss cable.

Please Justin, my pictures and screenshot are intended only for free hamradio publication.

73 and ciao.

The Analyser plots showing the antenna being well below 1.1:1 from 144MHz to 146MHz

Having spent hundreds of hours modelling AND mechanically testing Yagi arrays, no one is better positioned to give accurate, replicatable Yagi antennas for hams than G0KSC.

If you want the best in performance, want an antenna optimised for signal to noise ratio (giving you the ability to hear) rather than a 'splatter-pattern' Gain based Yagi, look no further, you have come to the right place!
