Ken:

When I put up Rohn 25 at my first QTH I bolted 2 sections together, made 
sure they were  plumb, and tied them off in several directions before 
pouring the concrete.
As the concrete as being poured I constantly rechecked the bottom 
section with a level to make sure it stayed plumb and tightened/loosened 
any of the support ropes to make sure it stayed plumb.  Did same as the 
concrete was drying although little/no movement was detected after the 
concrete was poured.  
I buried about 4-5 feet of the 1st section.

Also I put a several inch layer of river rock/gravel in the bottom of 
the hole and set the legs of the bottom section into it about a foot 
inches or so to allow for drainage, even though freezing is not that 
much of a worry in Texas.  Lets any condensation that forms inside the 
legs to drain out.
