To protect your house and your TV installation, your antenna system must be properly grounded.
1, Clamp a#10 copper or #8 aluminum grounding wire to the base of the antenna mast. Using stand-offs every 1.2m to 1.8m /4 to 6 feet, run the wire down the building in as straight a line as possible. 2, Attach a 300-Ohm static discharge unit (lightning arrestor) or a 75-Ohm grounding block to the antenna’s lead-in cable as close as possible to the point where the cable enters the house. 3, Attach the grounding wire to the lead-in cable’s grounding unit and run the wire to the central building ground.
Acceptable central building ground points may include: Grounded interior metal cold water pipe within 1.5m/ 5 feet of the point where it enters the building Grounded metallic service raceway Grounded electrical service equipment enclosure 2.4m / 8foot grounding rod driven into the ground (only if bonded to the central building ground by #6 or heavier bonding wire) Other acceptable electrodes that comply with the sections 250 and 810 of the National Electrical Code (NEC)
