Bob's comment about salt air not liking ceramic capacitors applies to any antennas insulator. 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. Stuart K5KVH |
