Safety precautions

ARNING!

• Installing antennas is dangerous. For your safety, follow the installation directions.

• Keep the antenna away from power source, street lamps, distribution box, or other places that may

cause electrical shock.

• Do not touch any power lines for your safety.

• Keep safety in mind when you select your installation site. Keep the antenna away from electric

power lines and other lines.

• Do not work alone when you install the antenna.

• If you need to raise the mast, work with other people to avoid bodily injury.

• 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.

• If an accident, for example, electrical shock, occurs with the power lines, immediately call for

qualified emergency help.

Installation guidelines

The ANT-2503C-M2 is designed to be mounted indoors on a ceiling to maximize its

MIMO-omnidirectional propagation characteristics. Install multiple antennas where necessary because

doors, windows, and walls degrade signal quality. Keep the antenna away from metal obstructions and

wire mesh.

Choosing a mounting location

The ANT-2503C-M2 is typically mounted indoors on the ceiling. Keep the antenna away from metal

obstructions such as heating and air-conditioning ducts. Typically, the higher an antenna is above the

ground, the better it performs. If possible, use a cable as short as possible to connect the antenna and

AP.

Mounting the antenna

You can mount the ANT-2503C-M2 antenna on a ceiling. The installation accessories are provided

(installation tools are user supplied). If you intend to mount your antenna on another surface, you must

provide the appropriate installation accessories.

Tools and accessories required

Provided with the antenna:

• One split flat washer

User-supplied:

• One adjustable wrench

Manual Version:5PW100-20120627

• One electric drill and associated drill bits

Mounting the antenna on a ceiling

To mount the antenna on a ceiling:

1. Drill an 18 mm (0.71 in) diameter hole in the ceiling where you want to mount the antenna. See

callout 5 in Figure 7.

2. Remove the flat washer (callout 3 in Figure 7) from the antenna and place it above the ceiling.

3. Thread the antenna cable through the hole you drilled in Step 1 until the base of the antenna is

flush with the ceiling.

4. From above the ceiling, thread the antenna cable through the opening on the split flat washer.

See Figure 6.

5. Thread the split flat washer through the antenna’s thread and fasten it until the antenna is secured

in place.

Recommended cable

H3C recommends that you 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).
