Aluminum is immune to salt all by itself. Zinc and aluminum is bad. Mixing metals causes electrolytic corrosion. Corrosion bad.
Same point I was trying to make about foam. It WILL cause corrosion because moisture will build up between foam and metal and never dry out, causing corrosion. The engineers who designed the antennas would have put in foam if it was a good idea. ( reference the rope idea)
