17. POWER LINES
(APPLIES TO TUNER AND RECEIVERS ONLY)
An outdoor antenna should be located away from power lines.
18. OUTDOOR ANTENNA GROUNDING
(APPLIES TO TUNER AND RECEIVERS ONLY)
If an outside antenna is connected to the receiver, 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 of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna-discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode. See Figure.
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
stand-off insulators spaced from 4-6 feet (1.22-1.83 m)
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 )
