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 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.
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.
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.
