[TowerTalk] Mast Material

[Timothy A. Holmes]

HI Folks:

I have been blessed with 30 feet of tower given to me by a friend.  its 
in good shape consisting of 2 regular sections and a top section.  I 
also have a very solid base in place that will support it and it will be 
tied to the house at 12 feet up.

My question now is the mast to go in it.  I have looked at the very 
heavy duty mast such as marketed by DXE and others.  Fantastic stuff, 
but quite expensive.  I am wondering about an alternative material. 
Such as thick wall electrical conduit (AKA EMP).  What I would like to 
do is make a LONG mast so that the rotor is at a height that is 
accessible at the ground, and run it up through the tower and out the 
top with about 10 - 15 feet showing out the top.

It will be carrying a 3 element tribander, 3 element 6m beam, a 9 
element 2m beam and something yet to be determined on 440. (Probably not 
real huge)

I need your thoughts and input, obviously I dont want it to fail and 
damage anything

Thanks a bunch
