A couple of possibilities for losing signal in the same area: local sources of radio frequency power interfering with the satellite signal. Satellite power is very weak, so XM also uses repeaters on the ground. So if a harmonic of a local radio/radar signal falls into the freq. range of the satellite or it's many repeaters, that stronger signal may blank out the XM signal. Airplanes/airports/fire/police/TV towers are all possible sources of strong RF signals. An example in your house of this is a microwave oven interfering with your router wifi.
Another more likely issue may be a blank spot in the broadcast signal. RF is easily reflected in ways that can cancel out transmissions. If a signal bounces off a building some distance away and then arrives at your location 180 degrees out of time with the direct signal, the two will cancel out. So signal strength is not at all uniform.
