Just to clarify, he's talking about an Avanti here; having an
all-fiberglass body, suppressing ANY source of noise is of utmost

I did not realize it was an Avanti. In that case, I think I would be
worried less about noise issues than making sure the radio antenna had
a proper centerpoise, because it can't use the metal body. The more
_signal_ you get, the more noise you can live with.
