Tom, my dome was located a few feet behind the old regular crank up antenna, on an aluminum base. We removed the dome, turned the aluminum base about 5 degrees to allow alignment of the HD antenna, resealed the old aluminum base and HD antenna base, drilled a new hole in the roof above the dash to run the wiring, and finally covered and sealed the wiring harness. If I was starting from scratch, I would locate the HD antenna nearer to the front since a new control wiring is required and it has to enter the coach somewhere, so I chose a hole over the passenger side of the upper dash.
