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-M3 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-M3 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-M3 antenna on a ceiling by using bolts or a T-rail. 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

• Accessories provided with the antenna for bolt-mounting:

{ One paper mounting template

{ Two M6 bolts

{ Two M6 hex nuts

Manual Version:5PW100-20120627

{ Two 6 mm (0.24 in) diameter flat washers

{ Two 6 mm (0.24 in) diameter spring washers

• Accessories provided with the antenna for T-rail mounting:

{ One paper mounting template

{ Two clips fastened on the antenna

{ Two mount clamps

• User-supplied tools:

{ One adjustable wrench

{ One electric drill and associated drill bits

Mounting the antenna on a ceiling

The ANT-2503C-M3 antenna can be mounted on a ceiling by bolts or a T-rail.

Bolt mounting

To mount the antenna by using bolts:

1. Use the paper mounting template to mark the holes on the ceiling where you want to mount the

antenna and then drill five holes in the ceiling. See Figure 6.

Figure 6 Paper mounting templa

2. Thread the two M6 bolts into the screw holes at the antenna base (see Figure 7) and fasten them.

3. Thread the antenna cable and M6 bolts through the holes you drilled in step 1 until the base of the

antenna is flush with the ceiling. Thread the M6 hex nut, flat washer, and spring washer (callout 4

in Figure 8) th

rough the M6 bolt (callout 3 in Figure 8) and fasten them until the antenna is secured

in place.

4. Fasten the other M6 bolt with the other set of M6 hex nut, flat washer, and spring washer.

T-rail mounting

To mount the antenna by using a T-rail:

1. Use the paper mounting template to mark the holes on the ceiling where you want to mount the

antenna and then drill five holes in the ceiling. See Figure 9.

2. Fasten the mount clamps to the T-rail as shown in Figure 10.

3. Thread the antenna cable through the holes you drilled in step 1 until the base of the antenna is

flush with the ceiling.

4. Fasten the clips to the mount clamps until the antenna is secured in place. See Figure 11.

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).
