The VRD-1FF is what you need.
The ground they provide give lighting or other dangerously high current a place
to go besides through the cable line but when I complain about noise, they
always said it's normal and won't deal with it.

BTW, I looked outside where they have their box on the side of my house and
the only ground I saw was a wire going from the box to conduit of my main
a/c feed from the breaker box? Is this normal?
