Reno, this is one reason I like a driven rod, adjacent to the utility entry. Even if you have other robust grounding electrodes the rod gives the cable co, telco and satellite guys a good, unambiguous, place to bond their entry protectors.
If I see the other utilities driving rods I make sure they get bonded to the service GES.
Sometimes you have to fight with the telco droid about this. They don't believe the electrical inspector can tell them anything.
Usually a call to the telco engineering department fixes this.
