Antennas

Outdoor antenna grounding

If an outdoor antenna or cable system 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 810of the National

Electrical Code 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.
