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?

The only point at which corrosion will affect the performance of the antenna
is if the corrosion has gotten into any of the mechanical joints of the
antenna. Corrosion on the elements will not be a factor.



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?

Matters not a bit.
