I built a 50' mast of this very stuff...chain link fence top rail, starting
with about 2 1/2" or so at the bottom and tapering to 1" at the top. A falling
derrick method is the best way to get it up, but I actually built a truss to
keep the majority of the length of it "straight", and just picked it off the
ground at the halfway point and walked it up, while a friend pulled one of the
guy ropes to help out when it got over 45 degrees. I use a four guy system
at two levels, 25' and 40' (I think). When you start pricing the pipe required
for this you will find it is cheaper to buy a ready make mast like the Tessco.
However if you have the stuff lying around, it works great.

If the goal is just to get something up to 44-50 ft... rather than a
push up mast (which has the advantage of small storage size and being
able to be pushed up within a small area), why not something like a
couple lengths of galvanized fence top rail with a coupler, or two
different sizes with a reducer. Lift it up (falling derrick works
well), and guy it off..
