Antennas
The antenna required for good color RPTV reception are more important than those for black & white television
reception. For this reason, a good quality outdoor antenna is strongly recommended.
A good color picture depends on a strong TV signal. Ask your dealer for advice on how to install your external
antenna to receive the best possible signal.
If you subscribe to Cable or Satellite TV or have a central antenna in your building, you may not need an external
Antenna.

Television Antenna Connection Protection
External Television Antenna Grounding
If an outside antenna or cable system is to be connected to the RPTV, make sure that the antenna or cable system
is electrically grounded to provide some protection against voltage surges and static charges. Please refer to the
operating or operation manual of your antenna or cable system for further information.
Article 810 of the National Electrical Code, ANSI/NFPSA 70, provides information with regard 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.
Lightning Protection
For added protection of the RPTV during a lightning storm or when it is left unattended or unused for long periods
of time, unplug the RPTV from the wall outlet and disconnect the antenna or cable system.
Power Lines
Do not locate the antenna near overhead light or power circuits, or where it could fall into such power lines or
circuits.
