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

To ensure the best possible performance of the antenna, follow these guidelines:

•Install the antenna vertically and make sure the antenna bottom faces downwards.

Manual Version:5PW100-20120627

•Keep the antenna away from metal obstructions such as heating and air-conditioning ducts.

•The density of the wall materials determines the number of walls signals can pass through and still

ensure data communication. Consider the following before choosing the location to install the

antenna:

{Signals can penetrate vinyl and paper walls with little affect to signal strength.

{Signals can penetrate one or two solid or pre-cast concrete walls with signal strength not

degraded.

{Signals can penetrate three or four concrete walls with signal strength not degraded.

{Signals can penetrate five or six wood walls with signal strength not degraded.

{Signals cannot penetrate a metal wall even if the metal covering is very thin.

{Signals cannot penetrate a wire mesh spaced between 2 and 3 cm (0.79 and 1.18 in).

•Keep the antenna away from microwave ovens and 2-GHz wireless phones, because they operate

in the same frequency range as the device to which your antenna is connected and can cause

signal interference.

Choosing a mounting location

To achieve best possible performance, install the antenna as high as possible, such as building top,

mountain top, and tower top. In addition, mount the antenna clear of any metal obstructions to the sides

of the radiating element, and use a cable as short as possible to connect the antenna and AP.

Mounting the antenna

You can mount the ANT-2011P patch antenna on a mast. 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

•One mounting kit provided with the antenna:

{One antenna bracket

{Four sets of M8 screws, 8 mm (0.32 in) diameter flat washers and 8 mm (0.32 in) diameter

spring washers

{One bolt with three M6 nuts

{Two mast-mount clamps

{Two long bolts with nuts

•User-supplied tool:

{One adjustable wrench

{One mast with a diameter of 40 to 70 mm (1.57 to 2.76 in)

Mounting the antenna on a mast

1. Remove the bolt (callout 3 in Figure 4) from the antenna bracket (callout 2 in Figure 4). Use the four

M8 nuts, four flat washers, and four spring washers to attach the removed antenna bracket to the

antenna. See callout 1 in Figure 4.

Manual Version:5PW100-20120627

2. Attach the antenna bracket to the mounting kit with the bolt you have removed. Start three M6 nuts

(callout 6 in Figure 4) on the bolt and tighten the nuts with an adjustable wrench.

3. Remove the two long bolts (callout 5 in Figure 4) from the two mast-mount clamps (callout 4

in Figure 4). Place the two mast-mount clamps around the mast and pass the removed bolts through

the holes on the mast-mount clamps.

4. Start a nut on each end of the bolts and tighten the nuts with an adjustable wrench until the

mast-mount clamps are secured in place.

5. Make sure the polarization arrow (callout 2 in Figure 5) is pointing up.

6. Rotate the antenna to make it point towards the other antenna with which your AP is to

communicate.

Adjusting the antenna bracket can change the vertical orientation of the antenna.

Adjusting the mast-mount clamps can change the horizontal orientation of the antenna.

7. Connect the cable and weatherproof the antenna connection.

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).
