Why not ask DX0-engineering - they sell large masts of
up to 65 feet and sell aluminum tubing for masts.
I just erected their 43 foot alum mast antenna. Why ask
them? They can say what they sell.
After doing this with a mast that starts with 2 inch tubing and
works down to about 3/4 inch, I think you are pushing it, but
it IS possible. I think you need to ask DX Engineering if they
have what you need.
