Safety precautions

 

WARNING! ·     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

Antenna can transmit and receive signals which are susceptible to obstacles and interferences. To ensure the best possible performance of the antenna, follow these guidelines:

·     Install the antenna vertically and make sure the antenna bottom is facing downwards.

·     Keep the antenna away from metal obstructions such as heating and air-conditioning ducts. Use the rigid cable to connect the antenna if necessary.

·     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 or wood walls with signal strength not degraded.

?     Signals can penetrate five or six drywalls or 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 install the ANT-2015P antenna on a mast. Installation accessories for mounting the antenna on a mast are provided.

Tools and accessories required

·     Provided with the antenna:

?     One set of JM-VB mast-mount clamps

·     User-supplied:

?     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.     Attach the antenna to the mast-mount clamp.

2.     Place the mast-mount clamp around the mast and adjust the orientation of the antenna (+30 degrees to –30 degrees). Then fasten the mast-mount clamp to the mast.

3.     Connect the cable to the antenna 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).
