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.

•

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.

Choosing a mounting location

Keep the antenna away from obstacles and metallic objects such as heating and air-conditioning

ducts, large ceiling trusses, and primary power transmission systems.

Typically, the higher an antenna is above the ground, the larger the signal coverage area.

If possible, use a cable as short as possible to connect the antenna and AP.

Mounting the antenna

You can mount the ANT-2503CM antenna on a ceiling or on a wall. The installation accessories are

provided with the antenna (installation tools are user supplied). If you intend to mount your antenna

in a way other than what is described in this document, you must provide the installation accessories

yourself.

Tools and accessories required

•

Accessories provided with the antenna:

Two wall anchors

Two screws

Two curved spring washers

One cable

Two bolts

•

User-supplied tools:

One screwdriver

One electric drill and drill bits

One pencil

Mounting the antenna on a ceiling

1. Use a pencil to mark the screw positions on the ceiling where you want to mount the antenna

and then drill three holes in the ceiling. See Figure 4.

Figure 4 Drilling holes in the ceiling

2. Thread the antenna cable connector and bolts through the three holes you drilled in step 1 until

the base of the antenna is flush with the ceiling. See Figure 5.

Figure 5 Mounting the antenna

3. From above the ceiling, slide the spring washers down the bolts and fasten them until the

antenna is secured in place. See Figure 6.

Figure 6 Securing the antenna

Mounting the antenna on a wall

1. Use a pencil to mark screw positions on the wall where you want to mount the antenna and then

drill three holes in the wall. See Figure 7.

Figure 7 Drilling holes in the wall

2. Insert the wall anchors into the two 7 mm (0.28 in) holes in the wall. Then thread the screws

through holes in the antenna. See Figure 8.

Figure 8 Mounting the antenna

3. Insert the screws into the two wall anchors and fasten them until the antenna is secured in place.

See Figure 9.

Figure 9 Securing the antenna

Recommended cable

As a best practice, use a high-quality, low-loss cable with the antenna. Coaxial cable loses efficiency

as the frequency increases, causing signal loss. Keep the cable as short as possible because cable

length also causes signal loss (the longer the run, the greater the loss).
