Presumably, the part sentence "your rig has an earth connection and that is your protection" refers to a connection to the a.c. mains earth.
So if the rf earth is not to be connected to the mains earth, how do you suggest that is to be achieved, since that 'rf earth' will be joined to the metalwork of the rig . . . which will be at 'mains earth'?
I did make a suggestion in my post 23 to solve that conundrum, but, judging by its responses, it seems that it was not a good idea.
Perhaps I've misunderstood you, or that I've missed something obvious (not unusual  )

Hi
Common question, simple answer.
If one adds a cable from the coax at the rig( rig ground) to earth then that cable becomes part of the antenna and that is not desirable and can introduce rf in the radio room
