Default Relative strength: single-wall or nested aluminum tubing?

Hi Bert,

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.

Is this a vertical run, or horizontal run?


It's vertical.
