NEC (National Electrical Code) Standards

A Note for the Cable Television (CATV) Installer

This reminder is to call the CATV system installer’s attention to Article 820-40 of the NEC that pro- vides guidelines for proper grounding and in particular, specifies that the cable ground shall be con- nected to the grounding system of the building as close to the point of cable entry as practical.

Antenna Grounding Outside the House

If an outside antenna is connected to the receiver, 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 lead-

in wire to an antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See diagram below.

Always observe proper antenna or satellite dish grounding techniques. When lightning strikes

there is always the possibility that your antenna or dish (mounted high on the roof) can

become a conduit for lightning and electrically damage any equipment to which it’s connected.

Additionally, proper grounding offers safety to the people using the audio/video system in the

event of an electrical problem.
