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.
