I installed it per the included instructions, which by the way, were much better than the Sirius factory instructions. Sirius failed to mention anything about luggage racks causing problems with reception. (It's a positional thing...) I'm a lifetime subscriber, mostly listen to Howard 100, and if there were dropouts, you'd miss important information. With this antenna, I have experienced zero dropouts! I'm a happy customer!
