[TowerTalk] Rohn 25 Vertical & Guying

[Mike & Becca Krzystyniak]

Greetings,

   I have an option to put up 80m and/or 160m vertical antennas using Rohn
25 tower, possibly building out the 80m into a 4 square.

   On 80m, are there any advantages or disadvantages using towers sections
for the full height, or would say ~3 sections topped off with ~30' +/-
tapered aluminum tubing to top it off work better?

   The other question I had was are there novel ways to provide an insulated
base with Rohn 25?  

Thanks in advance.
