70-1975, provides informationwith respect to propergroundingof the mast and supportingstructure,groundingof the
lead

-in wire to an antennadischargeunit, size of groundingconductors, locationof antenna dischargeunit, connection

to grounding electrode, and requirements for the grounding electrode.

15.2. Note to CATV system installer :(Only for the television set with CATV reception)
This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides

guidelines for proper groundingand, in particular,specifies that the cable groundshall be connectedto the grounding
system of the building, as close to the point of cable entry as practical.

16. Anoutsideantenna system shouldnotbe locatedin the vicinityof overheadpowerlines or other electriclightsor power
circuits,or where it can fall into such powerlines or circuits. Wheninstalling an outside antenna system, extreme care
sho

uld be taken to keep from touchingsuch power lines or circuitsas contact with them might be fatal.

17. For addedprotection for this television set during a lightningstorm, or when it is left unattended and unused for long
