Bear with me as I brainstorm out loud.
It sounds like the salt accumulation is very substantial at your QTH.
Another approach would be to figure out how to remove the salt on a
Assuming you have a source of pressurized fresh water on the island,
you could plumb a water line up the tower and connect to spray nozzles
that would rinse your tower, and possibly even the antennas.
Beats replacing it every 5 years. And all done from the ground. With a
