Outdoor Antenna Grounding:
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/NFPS No. 70-1983, 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 illustration below.
• Read Instructions: All the safety and operating instructions should be read before the appliance is oper-
ated.
• Retain Instructions: The safety and operating instructions should be retained for future reference.
• Heed Warnings: All warnings on the appliance and in the operating instructions should be adhered to.
• Follow Instructions: All operating and use instructions should be followed.
• Water and Moisture: The appliance should not be used near water. For example, near a bathtub, wash-
bowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc.
• Wall or Cabinet Mounting: The appliance should be mounted to a wall or cabinet only recommended by
the manufacturer.
• Heat: The appliance should be situated away from heat sources such as radiators, heat registers,
stoves, or other appliances (including amplifiers) that produce heat.
• Power Supply: The appliance should be connected to a power supply only of the type described in the
operating instructions or as marked on the appliance.
• Power Lines: An outdoor antenna should be located away from power lines.
• Object and Liquid Entry: Care should be taken so that objects do not fall, and liquids are not spilled into
the enclosure through openings.

Contained in Article 810-"Radio and
Television Equipment"
A. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminum, No. 17 AWG (1.0mm2) copper clad steel or
bronze wire, or larger as ground wire.
B. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4 feet (1.22m) to 6 feet
(1.83m) apart.
C. Mount antenna discharge unit as close as possible to where lead-in enters house.
