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.

And I forgot to mention --
I spray paint it all a flat black --- to help it blend in a little better!

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.

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.

And no matter how you disguise it with paint or whatever, it still looks
like an ugly piece of PVC because they are always naturally curved, limp and

Then what you have is a wooden structure with a PVC overcoat! The PVC is still
not the real structural material.

But if you fill it with the wood dowels, they stay relatively straight and also
won't get crushed by the antenna U-bolts.

I'm looking to put up a mast and am curious, why PVC? Is it better than steel?

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.

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
Again, you are NOT using the PVC for structural strength. Your strength is
coming from the wood! Big difference from using just PVC.

Hmmm... how about not being cheap and buy a steel or aluminum mast?
That's my solution
