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.
