[TowerTalk] AV-640 Vertical

[k6xr]

I had it's little sister the av-620. I installed per the instructions and
the bandwidth was within specifications. It did not outperform my g5rv at 40
feet and my solartron a-99 outperformed it on 15, 12, and 10 meters. I took
it down and gave it away. I had the cushcraft r4 and r5 and they worked
well. Also the gap challenger worked well for me.

I have been reading many years of Reflector Archives on TT, but have never
seen a post relating to the Hy-Gain "Patriot" AV-640 eight band vertical.
This is one of Hy-Gain's latest additions (several years back)of "no-radial"
end fed verticals that resonates on each band as an 3/8 wavelength radiator.
This is done with no traps, utilizing individual  3/8 wave radiators on 6,
10, 12, 15 & 17 meters with the main radiator operating on 20, 30 & 40
meters
using parallel top loaded coils and individual capacity hats. They use a
matching network (toroidal transformer & current balun)and 72" counterpoises
on the base for matching.

Going back through many years of publications, I found several "New Product"
tests that spoke "favorably" about the antenna's performance as long as it
is
mounted per the Hy-Gain's suggestions: at least 8' from ground and higher is
better.

Looking for any feed-back on this antenna. I've read all the views,
opinions,
about all the others: Butternut, GAP, MFJ-1792/1793, etc but nothing on this
series. Would this make a "decent" antenna for a "home, away from home"
setup
that has limited space available?  Thanks in advance.
