Never ever confuse your RF ground with a lightning ground, if lightning gets 
in to where your radio is and your RF ground because your lightning 
grounding outside isn't good enough, you have much bigger problems than 
you'll ever know, never ever use your grounding lug from your radio, tuner, 
amp, or what ever for lightning ground or even think it will serve that 
purpose. Lightning gets that far, you're in trouble and if you're in the 
room, you're probably lucky if you're not dead.
