Aluminum oxide is an excellent insulator.

I just bought a very old, verticle antenna. The ant. is aluminum and
very coroded.
Is this just a cosmetic problem, or will the corosion affect the
radiation/reception of RF?
Since the insulation on wire antennas doesn't affect their
effectiveness, I'm thinking the corosion wouldn't be a problem; but my
working-class logic has gotten me in trouble before. G
Will painting an aluminum antenna decrease it's effectiveness, or not
matter?
Thanx-
