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.
