[TowerTalk] Putting up BX & R-25 towers - Advise??

[DanW8KMX at aol.com]

Hello to all. I am new to the group.
I have read several of the archived messages and find conversations 
interesting and technical. Good job guys.

I am putting up a HD Rohn BX to 56 ft and a separate Rohn 25 to 60 feet. 
Although Rohn gives some guidelines on the cement base, much is not crystal clear. 
I had decided to overdesign the base and now have holes about 4 ft x 4 ft and 
6 feet deep. I am now ready to design the rebar system.

I am interested in your opinion about the size of the base and the rebar 
structure. Also any information regarding grounding would be appreciated.
