WHOA... RICK... You understand my position exactly.

Exactly. Darn it... At least the 6 and 10 meter
versions turned out well. It is just that the 20 meter
version is, as you say, under-dimensioned.

I am sure you are correct... I just hate giving up
on it as I have the tubing now. But it is just too
wobbly and flexible in the wind. I just need to
realize it and move on.

I agree. OR I need beefier tubing and a stronger

I now employ two such fiberglass poles to support
a medium aperture receive-only Wellbrook loop antenna.
They have held up well in the winter snow, ice and wind.

I already have a 43 foot aluminum multiband monopole
with 65 radials. Works rather well, actually, considering
all the inherent compromises.

Agreed on all objections.

Yes... It boils down to this -- I must either beef up
the aluminum so it is "stiffer" and does not wobble or
vibrate so much in the wind....or ... opt for a
lighter-weight support material (such as fiberglass)
that holds up well to ice, wind and summer heat.
The fiberglass may be the right tool for the job.
It would certainly be lighter and would probably
stand up to the wind without wobbling as much
as the aluminum tubing.
Thus... while I develop a fiberglass version of my
20 meter vertical dipole or ground plane... I should
stick up the 6 and 10 alum. dipoles I now have (which
are plenty study and tune to 1:1 with ease...) and
maybe string up the 40-6 OCF dipole I have built,
and continue developing the 20 meter antenna design.

My goal with the 20 meter VD or ground plane is to
finally have a really robust, study 20 meter antenna
that does not require a tuner/transmatch. I believe
it will be way more efficient than my big stick vertical

I have one of those now! Palstar AT-AUTO, as well as
the Palstar AT2K --- they work swell. The AT-AUTO
is a breeze to use. I think you will like it.

Perhaps, you could try a different wife... ;-)
THANKS for the specific reply - right on track.
