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 Hewlett-Packard 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.
