Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna ls connected to your tuner or tuner-preamplifier. be
sure the antenna system is grannded so as to provide some protection
against voltage surges and builtvup static charges Section 810 ol the
National Electrical Gods, ANSI/NFPA NO. 70-1984. provides information with
respea to proper grounding of the mast and supponing structure. grounding
at the leadin wire to an antenna discharge unit. size at grounding
conductors. location of antenna discharge unlt. connection to grounding
electrodes, and requirements tor the grounding eleclrvde.

a. Use No.10 AWG (5.3 rnm) 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 around wires to house with standott
Insulators spaced Imm 4-5 teal (1.22-1.83 m) apart.

a. Mount antenna discharge unit as close as possible to where lead-tn
enters house.

at. Use jumper wire not smaller than No6 AWG (13.3 mm) copper, or the

equivalent, when a separate antenna-grounding electrode is used. See NEc
Section sum in.
