That indicates failure to do proper bonding of the coax to ground before 
it enters the shack. If that's the case, it's likely that there are 
other bonding failures.

It's worth studying N0AX's ARRL book on the topic, to which I 
contributed, and/or this slide deck pdf for talks I've done at 
Pacificon, Visalia, and to several ham clubs.
