Outdoor Antenna Grounding
• If 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 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.
