2. 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 come into contact with power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep from coming into contact with power lines or circuits;
contact with them might be fatal.

IMPORTANT SAFEGUARDS AND PRECAUTIONS
OUTDOOR ANTENNA GROUNDING AND POWER LINES
1. If an outside antenna or cable system is connected to your VCR, be sure the antenna or cable system is
grounded, thus providing some protection against voltage surges and built-up static charges. Section 810 of
the National Electrical Code, ANSI/NFPA No.70-1984, provides information regarding 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. See diagram below.
