4IMPORTANT SAFEGUARDSExample of Antenna Grounding13 Power Lines — An outside antenna system should not be located in the vicinity of overhead power lines,other electric light or power circuits, or where it can fall into such power lines or circuits. When installingan outside antenna system, extreme care should be taken to keep from touching or approaching suchpower lines or circuits as contact with them might be fatal. Installing an outdoor antenna can be hazardousand should be left to a professional antenna installer.Use14 Cleaning — Unplug this product from the wall outlet before cleaning.

Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984 (Section 54 ofCanadian Electrical Code, Part 1) provides information with respect to proper grounding of the mast andsupporting structure, grounding of the lead-in wire to an antenna-discharge unit, size of groundingconductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements forthe grounding electrode. See following example.
