ANTENNA
WARNING
•
If you are using an outdoor antenna,
please install it away from electrical
wires to make sure it does not
touch any nearby wires even when
it falls down due to heavy wind.
- Failure to do so may cause
electric shock or physical injury.
CAUTION
• To prevent any water flowing into
the product, install a drip loop in
the outdoor antenna wire where it
comes indoors.
- Raindrops flowing into the
product may cause fire or
electric shock.
Outdoor Antenna Grounding
•
If an outdoor antenna 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 as death
or serious injury can occur. Be sure
the antenna system is grounded to
provide some protection against
voltage surges and built-up static
charges. Section 810 of the
National Electrical Code (NEC) in
the U.S.A. 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.
