K1VR adds:
EIA 222-F, Rohn, and others, recommend that the concrete base
rise six inches above grade. But an interesting thing happens if you put
your tower in the woods. Each autumn, leaves and pine needles fall. At
least they do in New England.
Result? Those leaves and pine needles, as well as any surface
"wash" if your tower is down hill from anything, can leave your concrete
base covered after a number of years. Now water can be left touching the
steel tower legs. From this point on, only bad things can happen.
Fortunately, this is a slow process, and you'll have plenty of time to go
back and re-read the many suggestions made on this reflector as to how to
repair and cover pitted galvanized steel.
