There are (or "were') sealed (that is; O-ring equipped shaft and hermetic
electric feed-through connectors) available. They are normally under military
specifications and fairly expensive unless you get they surplus. I guess they
should survive better in a rotor location.

John,
I agree the Vishay 10T pot does not seem to be a good solution. I
"worked" the pot back and forth more today and it never came back enough
to be able to use the RT-21 without the "no motion" error message
again. We did have a sever winter here in N. IL with a good amount of
precipitation. However, I just did a pot replacement and put the rotor
back in service September so I am very disappointed.
I am serious when I put the question out there to the TowerTalk
community. Has anyone considered or implemented a redesign of the TIC
ring rotor direction indication method to get away from the dreaded
unreliable pot?
