I think folks have pretty much taken care of the base issue.
I beleive the recommendations for grounding are to use solid wire, not stranded. If you can, use #2 or larger. The goal with grounding, if it is for lightning protection, is to get the lowest impedance possible to ground. Spread
Portland cement has no gravel. I'll mix it 4 parts to one.
So.those 15 94 lb bags are like 60 94 lb bags. I had figured I
needed 1.28 yards for the hole I dug. But now that I have the specs I
will see how big the hole has to be. I will only put a CPE on this
tower. Nothing huge.

Ya, I finally understood the diagram. I have to calculate my "w", "x",
and "d" to figure the base. http://www.wb0w.com/shelby/BXCBS1.htm

I think you have to get something like 7 yards to avoid all the
charges and fees for the truck. I guess I'll let you guys know in 2
months how it went. My brother does concrete for a living, so

That one has 7 sections and mine has 5. I never found the specs for
base. I'll keep looking.

Please read this and the manual from the site. You do not have nearly

Found it. But now I don't understand exactly how big my hole needs to be.

The same size as the one for the 70ft Version Brian - That's how large
of a base you need.
