To add to the thread I have a friend who has a semi repair shop. He has run PVC through out the shop for compressed air. He puts 150 psi through the PVC for air tools. I have played with PVC for a 2mtr mast. It worked pretty well. I want to use it in smaller sections for my satellite antennas which I don't to put up very high until I learn about the whole operation then I will place it on a roof with better material. I have the Yaesu 5500 rotor and that thing to me is heavy to lug around. Once it is on a roof with better materials it stays there until something breaks. I hope this helps.
