    Correct. And the concrete base's function is to basically keep the tower 
from sinking.

    Which alignment are you referring to? You mean horizontal levelness? 
Plumb? The easiest thing to do to insure plumb is to put nuts and washers on 
the anchor rods first, then the plate, and then another set of nuts and 
washers. That way you can use the bottom nuts as leveling nuts.
