To add strength to antenna mounting, I use something very simple.
I get large diameter washers, what we call fender washers.

I carefully lay them down in a pipe sawed in 1/2 lengthwise.

I beat them with a ball-peen hammer until they take on a curved
shape that fits the boom I need them for.  Curled, kinda like a
potato chip.  Drop them over the screw and onto the boom
before tightening.  Keeps the boom from flatening and allows
a good tight clamp.  Used this on a KLM KT-34A element
mount, and it held in 100+ MPH gusts here in Texas.  (Yep,
even the storme are bigger in Texas hi hi)  Hope this idea
helps someone.
