I already answered that. RF isn't DC ... it doesn't just flow to the
earth and disappear. It flows back and forth every half cycle. Whatever
current flow may occur between the coax and ground is still flowing on
the coax ... and since current doesn't just pile up on a conductor it is
going either back to the antenna or back to the transmitter. All you're
doing is probably changing the phase of it due to the capacitive effect
of the earth.
You ARE NOT just bleeding some static charge off to the earth.

Dave, I'm curious what you made of my antenna model that showed
common-mode current flowing to ground from the coax shield when
neither the antenna nor transmitter was grounded.
