Has anyone ever experimented with PVC pipe to use for a mast in place of
steel ? I have used it for vertical antennas and stands up excellent to the
winds and weather here in Toledo, Ohio .

Ted I added a AR2 preamp at the antenna ,it did not stop the birdy but it
allows me to hear through it{no duplex}.I cant hear my self until the signal
passes the birdy but signals are there With the preamp when I transmitt It goes
in bypass and the birdy wipes me out but in rx mode I can hear
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.

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.
Hi Ted,
I had the same problem, so never worked AO-27 and SO-50 years ago. Then
I took your approach, hooked up my IC-706MkIIG as the receiver, problem
solved. So then installed an antenna switch to move the 440 antenna between
the Kenwood and Icom. I programmed 145.850 in a memory for
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
PVC will help keep the SWR down by keeping the distance the antenna is from
another structure or possible ground that may cause an SWR or effect the
radation pattern of your antenna system. Use a wooden closet rod and insert it
inside the PVC pipe and put it up and enjoy.

First off, The originator asks a very open-ended question. His only

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.
