This has generated a lot of interesting talk, but I think most of it has missed the target.
My house has all incoming coaxial grounded at the outside wall using grounding blocks like pictured.
This is concerning coaxial cables coming from wallplates all over the house, into a single central closet where they will all be terminated, and where the DPP33 switch lives.
The question is, in this wiring closet, if all the coaxial shields are tied together in the central closet, do the resulting ground loops (which WILL form and conduct current through the ground shields) do these ground loops cause problems?
Hopefully it doesnt seem like "Much Ado About Nothing", it was expensive putting dual RG6 to every wallplate in the house, and its expensive terminating them all in the central closet, so I dont want to screw up here - at the very end - (of the projects and the cables ; )
