6.Section 810 of the National Electrical Code, ANSI/ NFPA No. 70-1984, provides information about the following items:
-Proper grounding of the mast and supporting structure.
-Grounding of the lead-in wire to the antenna discharge unit.
-Size of grounding conductors.
-Location of antenna-discharge unit.
-Connection to grounding electrodes.
-Requirement for the grounding electrode.
Note to the system installer: The purpose of this reminder is to call your 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. The illustration is an example of antenna grounding according to the National Electrical Code Section 810, "Radio and Television Equipment." Check your local building and electrical codes for other restrictions on antenna grounding.
