22. Outdoor Antenna Grounding - 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.
Section 810 of the National Electric Code, ANSI/NFPA No. 70-1984, provides information with
respect to proper grounding of the mats and supporting structure grounding of the lead-in wire to an
antenna-discharge unit, size of grounding connectors, location of antenna discharge unit, connection
to grounding electrodes and requirements for the grounding electrode. See Figure below.
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE
Note to the 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 6 English grounding system of the
building, as close to the point of cable entry as practical. Please, make sure to connect the power plug
to the wall outlet socket after connecting the TV to the adapter!
