INSTRUCTIONS
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected
to the product, be sure the antenna or cable system
is 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 grounding of the mast and supporting
structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conduc-
tors, location of antenna discharge unit, connection
to grounding electrodes, and requirements for the
grounding electrode.
2. Lightning
For added protection for this product during a
lightning storm, or when it is left unattended and
unused for long periods of time, unplug it from the
wall outlet and disconnect the antenna or cable
system. This will prevent damage to the product
due to lightning and power-line surges.
3. 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. When installing an
outside antenna system, extreme care should be
taken to keep from touching such power lines or
circuits as contact with them might be fatal.
