[Elecraft] KPA500 mobile?

[Fred Jensen]

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?
