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

·     Make sure the M6 hex nuts are tightened.

·     Once the antenna is fastened, its orientation cannot be adjusted. Make sure the drain hole in the antenna faces downward.

·     Attach a spring washer between a flat washer and an M6 hex nut.

·     A backing plate has been attached to the antenna base.

·     H3C recommends that you use a mast with a diameter of 40 to 50 mm (1.57 to 1.97 in).

Choosing a mounting location

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-2009Y Yagi 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

·     Accessories provided with the antenna:

?     Two mounting brackets

?     Two U-bolts

?     Four flat washers with an inner diameter of 6 mm (0.24 in)

?     Four spring washers with an inner diameter of 6 mm (0.24 in)

?     Four M6 hex nuts with an inner diameter of 6 mm (0.24 in)

·     User-supplied tools:

?     One adjustable wrench

?     One pencil

?     One mast with a diameter of 40 to 50 mm (1.57 to 1.97 in)

Mounting the antenna on a mast

1.     Place a U-bolt around the mast, and pass the U-bolt through the installation holes on the mounting bracket. See Figure 4.

2.     Thread the U-bolt through the mounting holes in the backing plate of the antenna and adjust the horizontal direction of the antenna.

Figure 5 shows the sizes of the backing plate and U-bolts.

3.     Attach a flat washer and a spring washer, and then start an M6 hex nut on each end of the U-bolt.

4.     Repeat steps 1 through 3 to attach the other U-bolt to the mounting brackets.

5.     Fasten the four M6 hex nuts with an adjustable wrench 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).
