Yes, they don't join until they get to an exchange or at least a cabinet (mine
is to a cabinet since I have fibre internet to the cabinet), where there
probably is grounding.

If you have cable TV, is there a ground there?

Can't tell you about cable TV, we don't have it here, we all use aerials or
satellite dishes.

We have Virgin Media cable for BB can't be doing with the telly and its
underground via ducts and no earths anywhere..


Oh yes there is! (Well, it IS panto season!).

There is an earth rod in every cabinet - it's all run by
electrickery, after all, so you wouldn't want it floating!

However, at the point of entry into the house, there is an
isolator which passes the signal but prevents any nasties in
the house from damaging the equipment in the street.

Here's a typical example:

That device says it includes surge protection, but does not show the
expected ground wire attachment point. My cable from the poles has a
smaller pass through device with a screw to tighten a ground wire into
it. I believe there is a filter at the power pole also.


It's likely designed to be used in a metal cabinet or housing which is bonded to ground. If used similar in a media distribution box in the house.
