[TowerTalk] 40 Meter Vertical

[Pat Chiles]

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.
