it is left unattended and unused for long periods of
time, unplug it from the wall outlet and disconnect
the antenna or cable system. This will prevent
damage to the unit due to lightning and power line
surges.
14. POWER LINES
An outside antenna system should not be located in
the vicinity of overhead power lines or other electric
light or power circuits, or where it can fall into such
power lines or circuits. When installing an outside
antenna system, extreme care should be taken to
keep from touching such power lines or circuits, as
contact with them might be fatal.

as they may touch dangerous voltage points or short
out parts that could result in fire or electric shock. Never
spill or spray any type of liquid into the unit.
17. OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected
to the unit, be sure the antenna or cable system is
grounded to provide some protection against
voltage surges and built-up static charges, Section
810 of the National Electrical Code, ANSI/NFPA 70,
provides information with respect to proper grounding of the mast and supporting structure, grounding
of the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna
discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
