Flat Earth Satellite Radio in a tunnel?

Driving through Washing, DC I had full Sirius Radio through this long tunnel. Also it works at the bottom of the parking garage at the ATL airport (under tons of cement!) Then it goes out sometimes when I’m near a tall tree or tiny bridge! What’s the deal? Anybody care to elaborate? Seems like reception is worse when cell tower reception is bad. Satellites? Hmmmmm?
