There *is* another alternative -- substitute a pier pin base for the
embedded section you were planning on. There's a lot of debate as to which
is better, but at least this way you don't need to worry about the tower
legs, because the only thing that goes in the concrete (other than rebar)
is the pin itself.
There is a full summary of an exhaustive thread on the pros and cons of
pier pin versus embedded sections to be found at KA9FOX's web page.
