I have a portable device in my Acura with an external antenna and I can drive through long tunnels and it never goes out. Oddly enough, it sometimes goes out in my garage with the door open.It is normal for any Satellite radio system in any car, portable device, or where you position the receiver in a home.
Definitely not the fault of your car.
I actually used to work for one of the companies that made the terrestrial repeaters and they make a huge difference...bad news is that Sirius hasn't covered many non-metro areas very well (they tried to do the cities with tall buildings first). So, if you live a more suburban or rural area, you will probably have "fade" from time to time under trees or even in storms.Living near a terrestrial repeater can be a big help. If I'm out in the boonies, I notice that trees and overpasses can have more of an effect. If I'm in the city or suburbs, however, and bathed in the warm microwave glow of the terrestrial repeater downtown, I find very few places where my service will drop out.
If you go to this page at DogstarRadio, it will show you where terrestrial antennas are located, and what area each effectively covers.
Boy u hit it on the head!Maybe there's something crappy about New Jersey. I mean, even more than usual. Because the complainers about Sirius reception are all from jersey.
