OUTDOOR ANTENNA GROUNDING

l1 an outside antenna is connected to your tuner or tuner-preamplifier, 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. ANSVNFPA No. 70-1964, provides intorrnation with
respect to proper grounding of the mast and supporting structure, grounding
ol the lead-in wire to an antenna discharge unit, size at grounding
conductors. location ot antenna discharge unit. connection to gmunrfing
electrodes. and requiremems lor the grounding electrode.

a. Use No.10 AWG (5.3 mm) 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.

b. Secure antenna lead-in and ground wires to house with slandwrt
Insulators spaced trom 4-6 last (1.22-1.83 ml apart.

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

a. use lumper wire nor smaller than No.6 AWE 03.3 mm) copper, or the
equivalent, when a separate antenna-grounding electrode is used. See NEC
Section 810-21 (1).

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV system installers attention to
Article 820-22 ol the National Electrical Code that provides guidelines tor
proper grounding and, in particular. speomes that the cable ground shall be
connected to the grounding system 01 the building. as close to the paint of
cable entry as practical.
