TELEVISION ANTENNA CONNECTION PROTECTION
TheTVshallbeinstalledinaccordancewiththeapplicableprovisionsofArticle810
andArticle820.
Ifanoutsideantenna/satellitedishorcablesystemistobeconnectedtotheTV,
makesurethattheantennaorcablesystemiselectricallygroundedtoprovidesome
protectionagainstvoltagesurgesandstaticcharges.
Article810oftheNationalElectricalCode,ANSI/NFPSA70,providesinformation
withregardtopropergroundingofthemastandsupportingstructure,grounding
oftheleadinwiretoanantennadischargeunit,sizeofthegroundingconductors,
locationofantennadischargeunit,connectiontogroundingelectrodes,and
requirementsofthegroundingelectrode.
Lightning Protection
ForaddedprotectionoftheTVduringalightningstormorwhenitisleftunattended
