"Bryan" wrote in message Pipe is
supplied in various "schedule" sizes, starting at 10. Common iron
plumbing pipe is malleable (low carbon steel) and usually Schedule 40.
So,
what are the actual dimensions? Try he
http://www.engineersedge.com/pipe_schedules.htm. So, commonly available
1-1/2" (1.90" OD) Schedule 40 would have a 0.145" wall thickness.

It is Schedule 40 pipe..This is not the best pipe to use, but should be
strong enough for me. The tribander is just over the top of the tower and I
doubt the other antennas will have much wind load. I live in the middle
of North Carolina so we do not usually get much ice or very high winds.
