We had a similar situation where the cable company did not ground their
cable to the AC Mains ground nor did they even provide a driven ground
for their system.
Probably around '89, when the home we bought in the Santa Cruz Mountains
15 years later was rebuilt, a telco installer ran the "ground" for his
drop on about 50 ft of #10 to the outlet for a garden hose, which was
fed by PVC pipe. The only earth connection was outside the kitchen of
the detached "mother-in-law" garage apartment (now my shack). The bond
from it to the panel in that building was #10 running up through the
ceiling across the building, down the outside wall, to a single driven
rod. I also found 120V outlets in that kitchen wired between one leg of
240V and the green wire.
Luckily, I didn't have lightning damage before finding these issues and
fixing them.
