[TowerTalk] Rebar schedule

[Don Bowen]

I am about to put up my tower I recently purchased used from the estate 
of a SK.  The tower is of unknown make.  The top sections look like and 
are the same dimensions as a Rohn except they are 9' long.  The sections 
telescope at the ends but are not held by bolts through the legs but 
rather by vertical bolts in short (<2") sections of tubing welded to the 
legs.  The base section is splayed out to 40" between the apex of the 
tower legs.  Mounting holes are drilled into pads welded to the legs on 
42" centers with straps welded from the pads to the center where they 
overlap and a hole is drilled.  Everything is hot dip Galvanized.

I was told I should have at least a yard of concrete in the base.  With 
the base spread and the frost line here I think the base will be 48" 
square by 30" deep.  What I want to know is this a good size and how 
much rebar should I have in the base.
