Semi-related curiosity regarding shielding. My wife's car has Sirius/XM
radio. It usually loses contact with the satellite driving under
Interstate bridges and the like. Likewise in the garage. OTOH, at our
previous home there was a tunnel through a small hill, perhaps 1/4 mi
long. The XM worked fine through it. There are a pair of tunnels at
Cave Rock next to Lake Tahoe through a granite mountain. XM works fine
through them too. Anyone know why?

When I take my 2011 Ford Focus through the car wash, I put the mag-mount
VHF antenna inside the car but it is still connected to the radio. I
have no problem picking up the usual 2- and 3/4- meter repeaters that
way. So much for the "Faraday Cage". :)
