Determining the Antenna Locations
1-8 Site Preparation
Additional Location Requirements
This section describes other requirements to meet before installing the RoamAbout 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.
• Antenna Height
If you are mounting the antenna on a roof, it must be at least 1.5 meters (5 feet) above the roof
line.
If you are mounting the directional antenna to a wall of a building, it must be high enough to
achieve a clear line of sight. Mounting an omni‐directional antenna to the side of a building
can cause signal reflection and reduce distance.
• AP placement
The AP should be located indoors, and connected to the outdoor antenna using the shortest
cable possible to reduce the loss of the cable.
Note: The installer is responsible for local building codes.
