Important Safeguards (Continued)
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 810 of 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.

line surges.
