Problem: How to inhibit corrosion of Rohn 25G steel tower in salt water
envirnoments.>>
Hi John,
Here's an unconventional treatment that may or may not be of some use.
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
regular basis.
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
solenoid valve arrangement, you could select one nozzle at a time for
max spray pressure, and to provide a sequence of spray from top to
bottom, following gravity.
You could have a single nozzle spraying up at the antenna and rotate
the antenna through the spray for complete wash.
Follow up with antiperspirant and some foo-foo, and your tower is ready
for action! <*grin*>. A shave might be a litle more challenging...
This in conjunction with a suitable coating could give you much more
tower life.
OK, just an idea to spur other solutions.
