CAUTION

TO PREVENT ELECTRIC SHOCK DO NOT USE THIS POLARIZED PLUG
WITH AN EXTENSION CORD. HECEPTACLE OR OTHER OUTLET UN-
LESS THE BLADES CAN BE FULLY INSEHTED TO PREVENT BLADE
EXPOSURE.

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

OUTDOOR ANTENNA GROUNDING

ii 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. ANSI/NFPA No. 70-1584. provides information with
respect to proper grounding oi the mast and supporting structure, grounding
ot the lead-in wire to an antenna discharge unit. size at grounding
conductors, location of antenna discharge unit, connection to grounding
electrodes. and requirements tor the grounding electrode.

3. Use No.10 AWG (5.3 mmi 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 stand-cit
insulators spaced from 4-6 feet (1.22-1.83 mi apart.

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

d. 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 (i).

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV system installer's attention to
Article 820% of the National Electrical Code that provides guidelines tor
proper grounding and. in particular, specifies that the cable ground shall be
connected io the grounding system ot the building. as close to the point or
cabte entry as practical.
