Build or buy one and compare to any brand, you will become a believer that
G0KSC have better designs and
what he claim is true, if you want numbers make the comparison against others
antenas
If you pay a little more attention to others publications or the web you will
notice that LFA is very popular in 6m and 2m EME
if not you just are using bandwidth in something you don't want to believe
Having several LFA's know what is the difference

Subject: Re: [TowerTalk] InnovAntennas contact info
I see a comparison for a single antenna out of their entire portfolio. That
one
comparison is against a competitive antenna of unstated boom length, and it
shows the InnovAntenna having the same maximum gain with a slightly wider
beamwidth, better front/side, and better front/back. Those factors may or may
not represent better noise performance depending upon what azimuthal heading
the
noise is coming from. If I assume that the noise is spatially uniform an
integral of those two plots looks like it would calculate out to be maybe one
or
two db in favor of the InnovAntenna. If the majority of the noise is coming
from a forward direction (such as when I beam eastward toward the sun) the
plots
look like the InnovAntenna would be about three db worse.
I'll accept the manufacturer's claim that the improvements in front/side and
front/back are the result of design flexibilities offered by a loop
configuration, but the net result doesn't seem to warrant the hyperbole and
that's been my only contention all along.
And yes ... I'll be sure to buy a subscription to another magazine so that I
can
research all the stuff that's missing from the manufacturer's own website.
