CAUTION

TO PREVENT ELECTRIC SHOCK DO NOT USE THlS POLARIZED PLUG
WITH AN EXTENSiON CORD, RECEPTACLE OR OTHER OUTLET UNr
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

If an outside antenna is connected to your tuna ut turret-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. 70-1984. provides information with
respect to proper grounding ot the mast and supporting structure. grounding
of the lead-in wire to an antenna discharge unit, size at grounding
conductors. location of antenna discharge unlt. connection to grounding
electrodes, and requiremems for 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) copperclad steel or bronze wire. or larger. as a
ground wire.

0. Secure antenna lead-In and ground wires to house with stand insulators spaced lrorn 4-6 feet (1224.83 tn) apart.

c. Mount antenna discharge unit as close as possible to where lead-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 (1).

NOTE TO CATV SYSTEM INSTALLER

This reminder is provtded to call the CATV system installers attention to
Article 820-22 of the National Electrical Code that provrdes guidelines for
proper grounding and, In particular. specities that the cable ground shall be
connected to the grounding system at the butlding. as close to the potnt oi
cable entry as practical.
