For 45G? According to the Rohn catalog, that's the recommended
configuration. One set up to 50 feet at 110 MPH. You do have a Rohn catalog,
don't you?

For this modest installation, I'd sink a section in the concrete base.
Four inches or so of gravel in the bottom for leg drainage.

How would that negate the need? You're still dealing with metallic guys
of some length and they will interact with antennas. Just because the tower
isn't very high doesn't mean that the metallic guy wire problems go away.
