Mast Head Units and Aerials
• The masthead connections of the VHF antenna cables and the
wind direction mast head unit should be checked at least once or
preferably twice during the season, or every time you work on the
masthead.
• If the electrical contacts are corroded, oxidized or badly connect-
ed, the instruments will not function efficiently.
• Corroded or oxidized contact surfaces should be cleaned and
sprayed with a contact-cleaner (e.g. CRC).
