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. See
diagram below.

Cable TV Coaxial Cable, Satellite Dish Cables, and
Television Antennas should be grounded BEFORE the
point of entry into the house.
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.
