Sirius Reception Issues?

I was in NYC a few weeks ago and the reception of Sirius was a real issue when driving around the city. I'm wondering if anyone else had the same issue with the radio looking for a signal when blocked from tall structures.

I've had the service for 6 years and this is the third vehicle with it and I've never had this problem in NYC. Before anyone tries to tell me that there are satellites in space and that you need line of site, well, yes, I, know, that. This would be an issue in lesser populated areas but major cities have local transmitters that take care of the lack of coverage above. NYC is the home of Sirius and DC XM and there is coverage within those cities when you have no sky view.

Do these radios lack the additional radio for non-satellite coverage? That would be a real flaw in this radio. Perhaps they had technical issues that weekend?

Re: Sirius Reception Issues?

I had xm before so I was just blaming Sirius but maybe you are right I get dropped signal in San Diego when driving on a street and pass a tall building the same building I passed many times with my other satellite radio and never dropped the signal

Re: Sirius Reception Issues?

There's no additional antenna needed to pick up the terrestrial repeaters; they're on the same frequency.

As for XM vs. Sirius system reception, XM satellites are in a higher orbit so it tends to take more to block them. Driving in a canyon-like city street lined by tall buildings will indeed do that.

I don't know if the Grand Cherokee is that much worse at picking up the Sirius signal; it doesn't seem too different than my Patriot was.

It's the other way around. The first three Sirius satellites are in highly inclined elliptical orbits so one of them is always at about a 60-degree angle. XM satellites are in conventional geosynchronous orbit, around 45 degrees up for most of us, and so have more trouble with concrete canyons. But since they don't move in the sky, fixed parabolic dish antennas can point at them. Sirius launched a fourth bird into geosync orbit to serve that market.

I lose signal driving among tall fir trees. There are a lot of tall fir trees in western Oregon.

Re: Sirius Reception Issues?

I have XM and it gets blocked by a 2 story building. IF their satellites are in a higher orbit than Sirius, that's not saying much.

Re: Sirius Reception Issues?

I loose the signal momentarily so often here in the 'burbs that I doubt I will buy it when my free year is over.

Geosynchronous is a higher orbit, but at a lower latitude (geosynch is over the equator). The Sirius HEO orbits at several thousand miles lower, but the elliptical nature gives a fair amount of loiter time over the continental US, and is also basically directly overhead.

But yeah, I goofed on the effect. The end result is that XM's signal is more easily blocked due to the angle.

Re: Sirius Reception Issues?

If I can tag along on this thread - new 2011 Grand Cherokee Limited - I loose signal passing under an overpass. My old honda Pilot (with XM) never had issues like the Jeep seems to have. Is it a bad antenna that Jeep put in or something?

Re: Sirius Reception Issues?

Not antenna issue. Depends how long you are under the overpass... just zipping under a 2 lane road, no... driving under wider roads or a series of overpasses, yes.

Re: Sirius Reception Issues?

I have one new car with XM and one (the Jeep) with Sirius. I don't know if it's the radio, the antenna or the service provider, but the Jeep loses signal far more frequently on the same roads than the other car. I thought my wife was just being a complainer, but I've found the difference to be quite noticeable. The Jeep's reception sucks in comparison. Again, all tested on the same roads. Any thoughts?

Re: Sirius Reception Issues?

I also have one with XM and the Jeep with Sirius. They both lose the signal briefly in the exact same locations. Mountain curves, some overhead wires and certain wireless devices interrupt the signal. I think it is more of a Sirius/XM problem than a Jeep problem. It happens very infrequently.

Re: Sirius Reception Issues?

This happens to me sometimes when driving in Brooklyn where buildings are not that tall. I didn't know Sirius has local transmitters.
