Safety precautions
WARNING
!
•
Installing antennas carries some level of risk. For your safety, read the following safety
precautions carefully before your operation.
•
Keep the antenna away from power sources, street lamps, power distribution boxes, or other
places that might cause electrical shock.
•Do not touch any power lines for your safety.
•
Keep safety in mind when you select your installation site. Keep away from electric power lines
and other lines.
•
Do not work alone when you install the antenna.
•
Do not use a metal ladder. Do not work on a wet or windy day. Dress properly, for example,
shoes with rubber soles. Wear rubber gloves.
•
If the antenna, antenna cable, or any other installation accessory drops, get away from it to
avoid bodily injury.

•
To avoid any potential hazards, always have a professional handle power connection rather
than attempting it yourself.
•
If an accident, for example, electrical shock, occurs, immediately call for qualified emergency
help.
Installation guidelines
To ensure optimal performance of the antenna, follow these guidelines:
•
Install the antenna vertically with the connector side facing downwards.
•
Keep the antenna away from metal obstacles, such as heating pipes and air conditioners.
•
The material and thickness of walls determine the number of walls that the RF signal can
penetrate. 5 GHz signal attenuation is large. Avoid signal penetration through solid walls.
Choosing a mounting location
To ensure optimal coverage, follow these guidelines when choosing a mounting location for the
antenna:
•
Perform site surveys to determine the antenna mounting location and height. Make sure no
obstruction, especially no solid walls and metal plates, exists between the antenna and the
target coverage area.
•
The antenna installation location must be as close as possible to the AP to reduce the antenna
cable length and signal loss.
•
The AP must be installed at a location where wires (cables or fibers) and power (local power
supply or PoE) can reach.
Mounting the antenna and lightning arrester
IMPORTANT:
When you apply weatherproof tape to
a cable connection, follow these restrictions and guidelines:
•
Make sure you attach the adhesive side of the tape to the connector.
•
Pull the tape as needed for overlap.
•
Start wrapping at the top of the connector, and overlap the tape to half-width. Avoid creases or
wrinkles and press the tape against the connection so that there are no gaps. Smooth each
wrapped layer with your hands to ensure full adhesion.
The antenna is installed outdoors. You must install a lightning arrester for it. The lightning arrester
can be installed on the AP or on the antenna connector. No lightning arrester is provided with the
antenna. Purchase one yourself.
To mount the antenna and lighting arrester:
1. Remove the weatherproof cap from the antenna connector on the AP.
2. Connect a lighting arrester to the antenna connector.
3. Connect the antenna to the lightning arrester.
4. Wrap each connection with weatherproof tape until the entire connection is wrapped. Smooth
the tape edges to ensure full adhesion.
5. Ground the lighting arrester.
