I haven't read all of the replies yet, but Teflon is a poor structural
material. If under compression or expansion it will move. It "cold
flows" substantially, like an extremely thick taffy. I used it for the
base insulator on a mobile antenna. In less than 20 miles the antenna
was swinging around at almost a 45 degree angle. I had to stop and guy
it into the car through the windows using heavy fishing line.
Delrin, or the strongest ...fiberglass painted with a UV protecterant
should work fine.
At least a few years ago, Array Solutions sold insulators for insulating the
base of Rohn towers.
Best to call, as I don't think I ever saw it on their web page.
