25. Installation of an external antenna - EXAMPLE OF ANTENNA GROUNDING AS

When installing an outside antenna to the PER NATIONAL ELECTRICAL CODE television 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.

For added protection for this television 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 collide with 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.

Note to CATV system installer: This reminder is provided to call the CATV system installer's attention to Article 820-40 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding

system of the building, as close to the point of cable entry as practical.”
