Your Antenna system must be properly grounded, in order to protect your house and your TV system

1. Clamp a #10 Copper or #8 Aluminum Grounding wire to the base of the antenna mast. Use stand-offs every 1.2m to 1.8m (4-6 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 (8 feet) 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)
