Hi,
The factory antenna was only a Sensar II and I bent it one day when I walked into it on the roof. I replaced it with the Sensar IV and chose black to go with the rest of the stuff on the roof. I only needed the head, the lifting arms were fine. Install was super easy - 1 coax connection and two bolts and done. I didn't really have a good basis to compare it to the old one, as we didn't use either very much. We had Dish.
