Is this a K7NV rebuilt prop pitch that is freezing? I thought that he
addressed water ingress in converting them into rotators.
Regarding heating, I have used silicone strip heaters in Ring Rotators with
great success. Another option is to move your tower further south.

I seem to be having some problems with my small prop pitch rotor freezing up
When the temperature is below freezing. I'm assuming it's a two part
First, water must be getting in somehow.
Second, the water freezes when its cold.
My rotor installation looks like the fifth picture at
So, first, how do I manage to reduce water ingress?
Second, how do I manage to heat the rotor? I don't have 120v at the tower
And it is about 400 feet from the house.
