Paul,
The 3 inch irrigation pipe would be a good solution. The people in
Farmville, Va see to be a pleasure to work with. I was designing an 80M
phased array and called them. The man I talked with was will to meet me
there on a Saturday even though they are closed. He was willing to cut the
long pieces to a size that could be easily transported with a pickup truck
and sell me just the right amount (5 ft sections) of a smaller diameter to
effect a good splice of the larger pieces.
Here is the info for contacting them. They also have a website.
