I just repaired (cleaned and reassembled) an antenna that had a problem with corrosion between the female chassis mount N connector and the aluminium plate it was mounted on. The connector was made of silver plated brass. Is there anything you can treat the connection with that will prevent this problem. I was thinking Alonox but I have no experience using this material and only know of using it with electrical wiring. Any suggestions would be appreciated.
