Coax grounding: If an outside cable system is connected to the unit,
ensure that the system is grounded.

NFPA No.70, provides information regarding proper grounding of the
mount and supporting structure, grounding of the coax to a discharge unit,
size of grounding conductors, location of discharge unit, connection to
ground electrodes, and requirements for the grounding electrode.
Power lines: An outdoor system should not be located in the vicinity of
overhead power lines, electrical lights, or power circuits, or where it may
contact such power lines or circuits. When installing an outdoor system,
extreme care should be taken to keep from touching power lines or circuits,
as this contact may be fatal. U.S.A. models only - refer to the National
Electrical Code Article 820 regarding installation of CATV systems.
