Note to CATV System Installer
This reminder is provided to call the CATV systems installer's
attention to section 820-93 of the National Electric Code,
which provides guidelines for proper grounding and in
particular, specify that the Coaxial cable shield shall be
connected to grounding system of the building, as close to the
point of cable entry as practical.
TV Antenna Connectors Protection
External Television Antenna Grounding
If an outside antenna or cable system is connected to the
product, be sure the antenna or cable system is electrically
grounded so as to provide some protection against voltage
surges and built-up static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides information with
regard to proper electrical 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.
Lightning Protection
For added protection of any product during a lightning storm,
or when it is left unattended and unused for long periods of
time, unplug the product from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the
product from lightning and power line surges.

Power Lines
An outside antenna system should not be located in the vicinity
of overhead power lines or other electric light or power circuits,
or where it can fall into such power lines or circuits.
WARNING: When installing an outside antenna
system, extreme care should be taken to keep
from touching such power lines or circuits as
contact with them could be fatal.
