OUTDOOR ANTENNA GROUNDING

ll an outside antenna IO oonnaotod to your tunor or tunarrpreamplifier, 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 intormation with
respect to proper grounding o! the mast and supporting structure, grounding
of the lead-In wire to an antenna discharge unit, size oi grounding
conductors, location at antenna discharge unit, connection to grounding
electrodes. and requirements lor the grounding electrode
a Use No.10 AWG (5.3 mm-) copper, N08 AWG (6,4 mm-) aluminum,
No.17 AWG (1 0 mm!) copper-clad steel or bronze Wire. or larger. as a
ground wire.

17. Secure antenna lead in and ground wire: to house wrth stand 0"

insulators spaced lrom 4-6 feet (1 22-1 83 m) apart.

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

d. Use jumper Wire not smaller than No.6 AWG (13.3 mm-) copper, or the
equrvalent, when a separate antenna-grounding electrode is used. See NEC
Section 310-21 (i).

NOTE TO CATV SYSTEM INSTALLER

This reminder is promoted to call the CATV system Installer's attention to
Article 520-22 of the National Electrical Code that prowdes gwdelines for
proper grounding and. in particular, specifies that tho cable ground shall be
connected to the grounding system of the building. as close to the pomt ol
cable entry as practical
