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?

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 a picture/drawing??
