My dish will be moving from the peak of the roof to one of three lower spots when we have a new roof installed. Since the skew won't change, I am looking at putting the mount elsewhere. But I would like to not be suprised at move time by knowing the acual footprint (or foot) size of the roof mount, and the actual diameter of the mast. I know some are 1.66 and some are 2 inches and I suppose this is 2 inches.
