Howdy,

In the 70's I worked on a project developing dual use small
boat radar. We had a terrible time with bearing corrosion at
first.

You might want to try wash-out resistant grease intended for
boat trailer wheel hubs.

In the radar we eventually used Andok C which is no longer
manufactured. Nye developed Rheolube 374C as a replacement
for Andok C. Both are an NLGI Grade 4 grease,

McMaster-Carr has a good selection of stainless steel bearings
and they have ceramic balls for bearings I believe. I'd want
to play with those a bit first before putting them up on a
tower.


73,
Grumpy

I've had good luck with a tight spiral wrap of ordinary vinyl tape.
Just took apart some connectors that had been up for more than a
decade and they were shiny as new. Lately I've also been filling the
insides with STUFF dielectric paste but I'm not sure this makes much
difference.
