Choosing a Mounting Location
•Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large
ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid
conduit to lower the antenna away from these obstructions.
•The density of the materials used in a building’s construction determines the number of walls the
signal must pass through and still maintain adequate coverage. Consider the following before
choosing the location to install your antenna:
–
Signals penetrate paper, vinyl and drywall the easiest. A signal can penetrate five or six walls
constructed of drywall or wood.
–
Signals are more heavily attenuated passing through concrete and solid-wood walls.
–
Signals often reflect off thick metal walls and may not penetrate at all.
•Install the antenna away from microwave ovens and 2-GHz cordless phones. These products can
cause signal interference because they operate in the same frequency range as the device to which
your antenna is connected.
Choosing a Mounting Location
The antenna should be mounted clear of any obstructions to the side or front of the enclosure. Keep in
mind that this antenna should be aimed into the intended coverage area, so you should mount the antenna
so that the desired mechanical tilt can be achieved. If possible, mount the antenna near the access point
so you can use the shortest possible connecting cables.
Installing the Antenna
You can install the antenna on any flat surface or on a pole with a minimum diameter of 2 inches
(5.08 cm) and a maximum diameter of 5 inches (12.7 cm). The antenna and one mounting flange are
connected together when shipped. When mounting the antenna you need to assemble the bracket
hardware, connect the antenna and bracket to the mounting surface, and adjust the antenna orientation.
