- 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.

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 conductors, location of antenna-discharge unit,

connection to grounding electrodes, and requirements for the grounding electrode.

- 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.
