My condo has a detached two car garage and the walls and tar & gravel 
roof are fairly RF transparent. My dev unit is in the spare bedroom and 
there is aluminum (or similar) in the walls and roof that does a good 
job of blocking both gnss and siriusxm satellite radio so the antenna 
(attached to window blinds) does not have a 360° view of the sky. 
Essentially it can only see out the window (which I believe has a UV 
coating that probably degrades the signal some amount.
