19 For US customers only:
Outdoor Antenna Grounding – If an outside antenna
is connected to this unit, 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 mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna discharge
unit, connection to grounding electrodes, and
requirements for the grounding electrode.
Note to CATV system installer:
This reminder is provided 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.
