I am a big fan of aluminum masts and I use them on both of my P40A towers
shown on http://www.qrz.com/p40a . They are not as strong as steel and they
do bend more so you have to make sure that you don't overload them with
antennas. I like them in my application because they corrode much slower
than steel. If there are antennae on your mast you should use a garden hose
to wash out the insects that crawled inside before installing it : )

I think I recall seeing a comment about mast, tubing and pipe.
Back in my early days, we used extruded 6061-T6 in 2 inch diameter with 1/4
inch wall. Many of us sprung for the tubing and put as much os 20 feet of it
out the top of the tower. It seemed to hold up and I don't remember anyone
having any problem with it.
That being said, I'm planning to put a tower with some HF antennae and I
found my old 24 foot 6061 mast in the barn. It's about 30 years old and
isn't even corroded. You know what I'm planning to do, so let me hear why I
SHOULDN'T use this. Especially after all the years of great track record
from the locals in southwestern Ohio.
