[TenTec] Station and AC Ground

Hey, All.

Just a quick observation and question.  I have read many posts on this site about having the station and AC mains grounds tied together.  For my observation, when you have a separate station ground (and I do; a good one) and all pieces of equipment are tied to that ground and the ground wire from the AC plug is tied to the equipment chassis then you have effectively tied the AC mains ground to the station ground.  I have measured from the AC mains ground to the station ground and it is zero ohms, with no voltage (to the microvolt between them).  I have looked in the equipment and the AC ground is tied directly to the chassis, not through a board.  My question is, if the equipment is grounded and you have a good AC mains ground is that not tying the mains and station grounds together?  I could see where one might have a problem if the ground in the equipment was achieved through a circuit board and the equipment was not otherwise grounded.  I feed two verticals, GAP Titan and Voyager, and run 1500 watts into them on a regular basis without any RF problems.  What say you?
