How good/bad are the Channel Master (9521A) antenna rotator's? Will they work with CB antenna's (5 element)?
Never heard of that one but it sounds like a light duty TV antenna type rotor. Is that it?
If so, it may be a bit too small for a 5 element CB antenna. A 3 element might be small enough to work but a 5 is going to be a bit big and heavy & wind load for a light duty TV rotor.
Good luck!
