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 elec-
trodes, and requirements for the grounding electrode. See diagram below.
