The picture you showed at the beginning of this thread looks like an old satellite antenna that was used for the Satellite receivers that were connected in line with the regular AM/FM antennas if it did work, I would presume it would only work for satellite reception if you can connect it to the radio and not necessarily On star. i personally would remove the radio and try it. What do you have to lose. Why did the dealership say the antenna was broken to begin with. Because it was hit by a limb? I don't believe that is the entire problem. You mentioned On star: Does that work? If so the problem may be with the radio itself.
