Probably not, but what is on either side of this "short run" that
loads this run with stress?

The rest of my antenna :-) About 25 feet of more aluminum.

It's actually a Hy-Gain AV-640, and the base tube is made of two nested
pieces of .058" tubing, but it's only a foot long, and I'm considering
some mounting options that would require a longer section that I'd have
to make out of stuff I can buy easily.

Hi Bert,

So it is at the point of maximum leverage - something to consider. As
it is vertical, then wind forces will be magnified at this point.
However, it seems you are doubling the length of what would have been
there anyway.

It still seems robust.
