Antennas

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.

WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM,
EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS
CONTACT WITH THEM IS ALMOST INVARIABLY FATAL.

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 USA and
Section 54 of the Canadian Electrical Code in Canada 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.
