EXPOSURE

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

OUTDOOR ANTENNA GROUNDING

ll an outside antenna is connected to your tuner or tuner-preamplifier, be
sure the antenna system is grounded so as to provrde some protection
against voltage surges and builtAup static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No. 704984, provides inlormation with
respect to proper grounding of the mast and supporting structure. grounding
of the lead-in wire to an antenna discharge unit, size ol grounding
conductors. location of antenna discharge unit. connection to grounding
electrodes, and requirements lor the grounding electrode

3. Use No.10 AWG (5.3 mm-) copper, No.8 AWG (84 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 Willi stand-oil
insulators spaced from 4-6 feet (1 ,22-1 .83 m) apart.

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

(1 Use Jumper wire not smaller than No.6 AWG (13.3 mm-) copper, or the
equivalent, when a separate antenna-grounding electrode is used. See NEC
Section 810-21 (j).
