You're welcome....
The roof antenna is raised with the crank handle on the bedroom ceiling. The outer ring of the circle is used to rotate the antenna. Once you get the antenna raised you can grab the outer ring portion and pull down to rotate in the direction of the best signal. There is an alignment mark on the outer ring and the ceiling. You MUST align those two marks before you drop the antenna down....otherwise it will come down off center and possible break it.
Needless to say....you need to make sure you check your antenna visually before you depart and make sure it's in the down position. There isn't any way to tell if it's up or down from inside the coach.
