I am currently working on completing a range of 2M Yagis which will have both metric and imperial tubing configurations. The G0KSC 9el 144MHz has been submitted and added to the VE7BQH G/T list and has performance unequaled by any other listed antenna of that boom length. Lionel, VE7BQH reports:

'it looks very good. Well done. Typically antennas this length are hard to get very good parameters in all facets. See where it fits in the table below. It is not until you get to a longer 2.35 WL boom is it equaled.'

'I was using my home made 5 el wide spaced yagi for 6 for some years now.
Worked allmost 150 DXCC with this antenna.
I designed it with some older software.
Found out that I was becoming more dependent of condx as it was also
becoming more crowded on the band.
So started to sea forrch a new antenna which meet my specs.
Soon I discovered your site and immediately felt that this was something
to try out.As soon as Vine had them commercially I ordered mine.
Put it up and found that compared to my old yagi the performance was
better, on both reception and transmition.
A pitty the season almost had ended but still managed to work some new
DXCC in the West Indies.Reports are fine and often I get through first in
the pile ups.I run no ampl. just 200 watts.
Not all the local trash has gone but  I think this is hardly possible
anymore these days, but surely it has improved.This means in my eyes with
a sharper foreward pattern and more sensitive antenna beiing able to
reduce noise is a dubble bonus.

My conclusion so far is that these yagi's rock , really perform in real
live.You have done a fantastic job !
As you can read on qrz.com I call it the first generation of LFA.
I'm curious to see what future will bring more on your designs.Saw that
with a trapezium shaped loop the pattern can be improved.
I'm keeping an eye on your site...

The -39 dB I measured was inside the shack, this means with 50 meter coax
and 2 1:1 coax choke baluns and a lightning arrestor in line.So when
measuring direct at the antenna feedpoint this would be better.Still have
to do this though when i have time.
