Directional Antennas
- Consider these factors when selecting a location
for these antennas:
•
For optimum coverage, mount the antenna above any obstructions,
directed at the center of the coverage area sector.
directed at the center of the coverage area sector.
•
High-gain directional antennas provide a flattened radio coverage
pattern in the horizontal plane. Use the tilting or articulated mounts
to point the antennas towards the coverage area.

Outdoor Installation
- When installing an antenna outdoors, be sure to
consider these additional factors:
•
Always place the antenna away from power and telephone lines
•
Make sure that the antenna, any supporting structure, and cables are
all properly grounded.

•
For lightning protection, consider using a lightning arrestor immedi-
ately before the cable enters the building.

Never install an antenna or construct a radio mast near overhead power lines.
2. Mount the Antenna
Install the antenna in its planned location using the brackets, clips, or other
hardware included in the antenna package.

and installation instructions.
3. Connect Pigtail Cables to the Access Point
Use the pigtail cables that are attached to the antenna, or are included in the
antenna package. If an extension cable is required, please contact a profes-
sional installer who is trained in RF installation and knowledgeable in the local
regulations.

Note that diversity antennas have two pigtail cables. A diversity antenna
includes two internal antenna elements that are identical. Both antenna pigtail
cables must be connected to the access point for correct operation.

Other non-diversity antennas, which have only one pigtail cable, attach to the
access point’s right antenna connector. The access point’s right antenna is the
one on the side closest to the LED indicators. When using a non-diversity
antenna, a 50-ohm terminator (included with the antenna) must be connected
to the access point’s left antenna connector.
