Important safety precautions

- If an outside antenna is connected to the equipment, be sure the antenna system is grounded so
as to provide some protection against voltage surges and built-up static charges.
Section 810 of the National Electrical Code 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.
EXAMPLE OF ANTENNA GROUNDING AS PER
NEC-NATIONAL ELECTRICAL CODE
- For added protection for this equipment 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. This will prevent damage to the equipment due to
lightning and power-line surges.
- 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.
