A number of years ago I purchased two 20' lengths of 2" square, 1/8" wall
fiberglass tubing for the boom of an LPD array that I never built. They have
been laying outside on the ground in the Arizona sun since then. They are still
as smooth as the day I brought them home. Contrast that to some of the mil
surplus fiberglass tubing sections that have gone in the trash in a shorter
time. The good stuff is made by Strongwell and is used for handrail systems.

After a couple of years, the push-up poles started to break down anyway and couldn’t be handled without gloves unless I wanted nasty fiberglass fuzz imbedded in my hands. They ended up going out in the trash.

These are very high quality products, which could easily be house bracketed to eliminate the need for guys, and much more suited to permanent installation. My mast (a 30-something ft HD version) was supported by a ground mounted rotator and guys, and held a Hex beam before I had to pull it down to sell my QTH. Not the same application, obviously, but an excellent quality product, and not outlandishly expensive.
