Hi David,

The cable grounding is to prevent the cable from arcing to objects 
where the cable is routed. Mains or RF ground will do for this 
prevention. If the cable has a high probability of strikes (strikes 
that reach floor fairly well), then I would likely tie the braid to 
RF ground. In either case, it's not safe to be handling the cable 
while the coil is operating.

Take care,
Bart
