Here is his original post

I have 3 sections of 25G, the top being a 25AG2. I would like to use a
12' piece of 2" OD .25" wall 6061-T6 aluminum tubing to get a total
height of around 40'. The antenna will be a 2E Steppir. My question
concerns running the aluminum tubing through the top of the 25AG2. Is
this a reasonable application? Can I expect a lot of wear on the tubing
when not using a thrust bearing? Will there be sufficient support for
the tubing in the rotator (a HAM IV)?
Thanks and 73,
Tom K7TBM

So our advice is - buy an extra 10 foot secton of Rohn 25 and use a short
mast section to support your Steppir. This will get you 40 foot plus and be
much stronger.
