There are a number of possibilities.
This is the most likely, but I'd think you'd be able to see some movement if only slight.
You could get some one to operate the rotor... Just bump it in one direction and then the other while watching the instalation. You should hear the motor and at least see it try.
Try the visual check and see what happens. Don't keep trying though and over heat the motor.Shouldn't the G-1000 be able to break through? The rotor does not slip against the mast. (Indicator does not move.)
What do people do to prevent this? Lubricate the sleeve, provide a weather shield, heating tape, ...?
Lubricating the sleeve is a kinda dicy proposition. There are some greases that will work, but they are messy and if you get water in the grease nothing will turn.
The mast should be a relatively loose fit, but not wobbly.
On ham in Alma MI took the top of a spray paint can, cut a hole in it to just slip over the mast. He slid the top down to the point where it extended down over the top of the sleeve nearly 2 inches. He then used Silastic RTV (TM) to seal it to the mast It made an excellent weather cover and has been in use for years.
Of course this method requires it be done before the antenna is mounted.
I've also seen pieces of innertube wrapped around the mast (at least two turns) so they flared out a bit and extended down over the sleeve by several inches. You can use a couple of SS hose clamps in this case to hold the rubber in place. They should clamp tight enough to keep water from getting inside and running down mast.
Now if I could just figure out how to get the water out of the motor on mine
Hey! The temperature is up to a balmy 28F and it works!Balmy 28? It was 7 below with a high of 8 to 10.
