[amsat-bb] where to get Fiberglass rod for elevation rotors

[James French]

Wondering if anyone can suggest where they got their fiberglass
elevation supports for antennas from?

I have a friend who is looking for longer pieces than I have for
a project and I can't find any of the info that has been mentioned
on the -bb over the years. Probably just not doing the right word
searches.

Thanks,
