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!

I don't feel that this is a particularly good example for the following
reason.
If, and only if, the ground point at the radio where the coax is terminated
to the radio is an excellent RF ground, then any current flowing on the
outside of the coax will be shunted to ground at that point. As it is an
excellent ground, impedance is low, and voltage will thus be low as well
.... ideally zero of course.
