Kelly..... I found pictures of the mount in the 20th ed of the ARRL Antenna
book. It appears that the way it was built was STRONG!!! Might be worth
finding a copy of the book and look at the pictures. I don't have a scanner so
can't copy it for you.

Subject: Re: [TowerTalk] U-bolt swivel
I can picture this in my mind, but isn't that a lot of stress to put
on the u-bolt and mast since you now have the entire weight of the
antenna pulling down on the "boom section" with no counter-weight on
the other side?

> Kelly, If my ageing memory serves me correctly, the PVRC came up with a
mount to do just this. I think it was even included in the ARRL handbook at one
time. Nothing more than a short "Boom section" attached to the mast, coming out
horizontally about 10" or so. Then you would mount the boom from the antenna
onto the stub by rotating the mounting plate horizontal (same plane as the
elements). Does this "rattle" anyone else's grey matter? Maybe point Kelly to
