OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner-preampiirier. 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 Electrical Code. ANSI/NFPA No. 70-1984. provides intom'iation with
respect to proper grounding oi 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 groundlng electrode.

a. Use No.10 AWG (5.3 min-) copper, No.8 AWG (8.4 mm-) aluminum,
No.17 AWG (1.0 mm-) copper-clad steel or bronze wire. or larger, as a
ground wire.

I). Secure antenna lead-in and ground Wires to house with stand-oft
insulators spaced lrom 4-6 test (1.22-1.83 m) apart.

c. Mount antenna discharge unit as close as possible to where lead-in
enters house

it. Use jumper wire not smaller than No.6 AWG (13.3 mm-) copper. or the
equivalent. when a separate antennagrounding electrode is used. See NEC
Section 810-21 (1').

This reminder is provided to call the CATV system installers attention to
Article 820-22 ol the National Electrical Code that provrdes 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 at
cable entry as practical.
