SAFETY INSTRUCTIONS
ANTENNA
Outdoor Antenna Grounding
yIf an outdoor antenna is installed,
follow the precautions below. An
outdoor antenna system should not
be located in the vicinity of overhead
power lines or other electric light or
power circuits, or where it can come
in contact with such power lines or
circuits as death or serious injury can
occur. Be sure the antenna system
is grounded so as to provide some
protection against voltage surges and
built-up static charges. Section 810
of the National Electrical Code (NEC)
in the U.S.A. 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.
