Gary - not sure what point you are making. Say we did have the perfect 
RF Ground at the radio, impedance zero, voltage zero. That's when the 
common-mode current is highest and when the radiation from the coax in 
the shack will be highest. Don't confuse  "zero voltage" with "zero 
radiation" - quite the opposite in this case!
