The antenna on my coach dates from 1998, possibly a RD4600. Forgetful me, I left the dish up and drove off. Hit a tree branch and must have turned it. It wouldn't park. Got on the roof and turned it to park. Next time I tried to raise it, it would go up, but not find anything. When it wouldn't park, had to manually turn the turret again to park it. Now it won't do anything, just go so far and then sound like a gear is slipping. Can it be realigned with the Pinnical positioner, or is it shot and need to be replaced.
