Answer Notes

Outdoor antennas and their associated cables act as massive lightning rods and collectors of static electricity. When your station is not in use, these exposed metal components pose a significant risk to your home and equipment if an electrical storm approaches. By grounding all antenna and rotator cables, you provide a safe, low-resistance path directly to earth for any lightning strikes or static buildup. This directs the destructive energy away from your expensive station equipment and significantly reduces the risk of electrical fires in your building.
