I have a situation on a Duplex apartment. It has 2 satellite dishes located on cantilevered decks. Each deck has 11/4" pvc conduit where RG6 enters the building and goes to each apartments media panel . My intention was to install a discharge unit with separate dual ground electrodes on the side that is farthest from the service entrance and what I think is the location for the supply system ground. (Ground rods) From what I have been reading, my idea requires a jumper from the supply system grounding to my communication grounding bar on the foundation. Internally in the building, one heavy ground cable originates under the concrete floor where it connects to the copper water pipe, then to the first breaker panel, then there is a jumper inside the first, which connects the second apartments panel.
My first question: Is this required bonding between the entrance grounding and my communication grounding bar? Can it be run inside the building, could it be just connected to either the ground in the breaker panel, or could it run and connect to the water piping within 5 feet of the piping entrance out of the floor? Also, this building was built in 1977, the neutral and ground bars in the panels are all combined.
My second question: I'm installing a media panel in the same building, and also putting in isolated ground outlets (GFCI as it is in the basement) for this media panel. Can the grounds for the outlets just connect to the water pipe, and the neutral to the breaker panels given they are combined in the breaker panel? What is the correct way to do these things. I know they are frequently incorrectly done.
