In the comments on this question (Using PEX as wire conduit), the issue of grounding shielded data cables on one end vs both ends came up.
For any arrangement of cables (ex. single cable, multiple cables into splitters/hubs, multiple parallel cables. etc.), how should they be grounded?
I am especially interested in both CAT6 (Ethernet) and coax (<3GHz) since I am actually about to run some underground between two different structures. In my case, both structures share a grounding electrode system, but an ideal answer would also address instances where this is not the case.
My current plan is to ground the coax on both ends with a grounding block and a grounding conductor going back to the nearest service panel, and to ground the CAT6, which is shielded, on both ends with surge protectors and a grounding conductor going back to the nearest service panel.
