A Few Words About Grounding
the DIRECTV PLUS™ System
Grounding the satellite system to the central building ground helps protect it and other
components from lightning damage. Dish installation should comply with local codes
and the National Electrical Code (NEC). Grounding the satellite system is something
you can probably do yourself. But if you’re not sure, you should contact a qualified
electrician.
Acceptable central building ground points
•
Grounded interior metal cold water pipe within five feet of the point where it
enters the building.
•
Grounded metallic service raceway.
•
Grounded electrical service equipment enclosure.
•
Eight-foot grounding rod driven into the ground (only if bonded to the central
building ground by #6 or heavier bonding wire).
•
Other acceptable grounding electrodes that comply with sections 250 and 810 of
the National Electrical Code (NEC).
IMPORTANT
The United States National
Electrical Code specifies
that coaxial cable that is
exposed to lightning shall
be connected to the
grounding system of the
building as close to the
point of cable entry as
possible.
