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

Hello Mike - I use schedule 40 PVC with an OAK closet pole down the center for added stiffness for a horizontal boom. For vertical mast I use two PVC schedule 40 - one inside the other - along with a wood pole. I use PVC end caps on the ends to keep water/ moisture out. 73, Bruce WA3SWJ At

I acquired a fair amount of windsurfer mast at a garage sale and have used it successfully as a mast for a 3 element 6M beam and also as a support for a 40M inverted vee with no problems yet. I have clamped two pieces together with hose clamps to get about 22 feet of height with no guying.

PVC is NOT a structural material. You can sometimes get away with using it for something like a vertical antenna without any real stress. However, using it to support something with any horizontal force is another matter. The colder the weather the more likely it is to fail. Making an A

It works well to fill a PVC pipe with a wood dowel the size of the pipe's inner diameter. Then you just need to weatherproof the ends of the pipe with caps or otherwise. 73, Ken N2WWD On Feb 24, 2011, at 10:58 AM, Glen Zook gz...@yahoo.com wrote: PVC is NOT a structural material. You can

But if you fill it with the wood dowels, they stay relatively straight and also won't get crushed by the antenna U-bolts. 73, Ken N2WWD On Feb 24, 2011, at 12:07 PM, Bob Bruninga bruni...@usna.edu wrote: PVC is NOT a structural material And no matter how you disguise it with paint or

did use the grey thick-walled PVC, not the white stuff. It's a perfectly acceptable material with the wood inside, non-conductive, non-rusting. 73, Drew KO4MA -Original Message- From: Matt Patterson mattp...@1starnet.com Sent: Feb 24, 2011 2:05 PM To: amsat-bb@amsat.org Subject: [amsat-bb

PVC is CHEAP! However, it has no real structural strength and, in cold weather, often gets brittle and fractures. PVC is made for carrying things like water and is definitely not made to be able to withstand any forces other than moderate pressure (i.e. water pressure). People do make things
