Bob's comment about salt air not liking ceramic capacitors applies to any
At sea or shore stations we have on Navy projects; a SOP to wash off
insulators with fresh water every morning! This was seen on a fiberglass
antenna as well, and a Sigma 5 from Force 12. The Force 12 is fine after
the rinse, and you drill a weep hole in the bottom of its "radome" at center
of antenna to drain the coils area of condensation overnite. Aboard ship, a
MFJ loop is used that also must be water cleaned daily.
The salt air and wind leaves a salt deposit on the insulators and conductors
and detunes the antennas.
