I mounted a satellite antenna on the roof of the 5th wheel we had before buying Rocky. That darn thing could always find a tree branch that blocked the signal! Many times we had to move the trailer a foot or two to get a clear signal. If I ever did it again, I'd stick with a portable dish that can be moved to find a clear view of the SW sky.
