There seems to be some experts in this group on grounding so I thought
I would ask a question.
I have timewarner install digital cable, however, there is now way for
them to run the cable into the house near the power ground.
Supposedly they are supposed ground to power or not come in, but in
this case they just couldn't do it.
So they ran the cable to the other side of the house for entry which
has no ground. The cable in my area is mostly underground (not on
poles).
So my question is what should I do to protect against lightning
strikes or should I do anything at all? Should I drive a grounding
rod into the ground and connect the cable to that before it enters the
house? Should I buy some sort of inline cable protection device (i.e.
a fuse type that would break the connection in case of a strike) to
put on the cable right as it enters the house before it goes to
splitting and other rooms? Should I not do anything at all?
I just don't want all my televisions and other devices to get fried.
I am assuming that anything plugged into the digital cable box could
potentially be damaged should enough energy travel through the coax to
the digital box and then out some of the output connections. I am not
worried about the digital cable box itself (it is owned by the cable
company).
The other issue is most of my audio/video components are plugged into
UPSs, so there could possibly be grounding loop issues.
Any direction would be appreciated from some of the experts in the
group.
