[quote=Kung Fu Jedi So, anyone out there have Sirius and can give me a report on how the reception is downtown, from inside a building? Any info would be greatly appreciated. Thanks![/QUOTE]
I have Sirius in my car. I've never tried to get their signal inside a building but I understand that it's iffy, at best. I think you would have to have an antenna at least near, if not outside, a window. In a car, when you drive under an overpass, you usually lose the signal momentarily. Under my carport -- a thin metal roof -- there is no signal. I even lose it sometimes driving under trees.
The key would be that repeater you mention. If it beams into your office, then that would probably do the trick. But that's what it would have to do, I think, because you are sure not going to get the satellite signal through the layers of a building.
I do really like Sirius. They have the NFL contract, with a year-round NFL Station. So, I can always get my football fix when I need it. It is usually said that if you like talk, sports, etc., Sirius has more of that, along with the music, while for people who just want to listen to music, XM may be a better choice.
But I would not buy either one for listening inside a building without trying it out first and, probably, making some provision for an outside antenna. I imagine there is a lot of info on this subject on the web, if you Google for it.
