Additional Location Requirements
This section describes other requirements to meet before installing the outdoor antennas.
•
Lightning Protection
A lightning rod must be placed close to the antenna mast or wall bracket. This is required to protect
the antenna from direct lightning strikes.
•
Grounding System
Direct earth grounding of the antenna and the lightning protector is necessary to protect the
installation from lightning and the build-up of static electricity. The wireless device and the lightning
protector must be connected to the same earth ground using separate grounds. The antenna and
the mounting structure require separate grounds to the same earth ground, using an equipotential
bonding conductor. Check with a certified antenna installer, or local electrician, to make sure the
antenna is properly grounded.
Ensure that the cable between the antenna and lightning protector is at least 0.9 meters (3 feet)
away from high-voltage or high-current cable. For more information about the lightning protector,
