Hi, I am new to rv's so this might sound dumb to . I was trying to raise my antenna , and it would not go up , I noticed that the spring just above crank is missing, could this be the problem? Look...
Crank handle is held onto worm gear drive shaft with an allen screw Then there should be a nylon washer Then the spring which presses against direction handle (ring)
Marks on direction handle and on ceiling plate should align for proper stowage of antenna (2 brackets that hold antenna posts when retracted)
After replacing/reinstalling spring,washer etc..might need to go up on roof and check if antenna is in a bind. Could also need some silicone lube sprayed on gear teeth and rotation base
