Requirements
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 arrestor is necessary to protect
the installation from lightning and the build-up of static electricity. The wireless device
and the lightning arrestor must be connected to the same ground. The antenna and the
mounting structure require a separate earth ground connection.
Check with a certified antenna installer to make sure the antenna is
properly grounded.
Line of sight
Spread spectrum systems for LANs are complete point-to-point systems and require a
clear line of sight from location to location. Zone widths of the beam depend on the
distance between the antennas. The defined radius is an area that is widest at its center.
The table below shows the zone radius required at 2.4 GHz.
