Safety Precautions

Translated versions of the following safety warnings are provided in the Safety Warnings for Cisco

Aironet Antennas, which is available at http://www.cisco.com.

Warning

Installation of this antenna near power lines is dangerous. For your safety, follow the installation

directions.

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of

these cases, the victim was aware of the danger of electrocution but did not take adequate steps to avoid

the hazard.

For your safety, and to help you achieve a good installation, please read and follow these safety

precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek

professional assistance. Your Cisco sales representative can explain which mounting method to use

for the size and type antenna you are about to install.

2. Select your installation site with safety as well as performance in mind. Remember: electric power

lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Call your electric power company. Tell them your plans and ask them to come look at your proposed

installation. This is a small inconvenience considering your life is at stake.

4. Plan your installation carefully and completely before you begin. Successful raising of a mast or

tower is largely a matter of coordination. Each person should be assigned a specific task, and should

know what to do and when to do it. One person should be in charge of the operation to issue

instructions and watch for signs of trouble.

5. When installing your antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or

jacket.

6. If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable,

and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any

of these parts to a power line completes an electrical path through the antenna and the installer: Yo u !

7. If any part of the antenna system should come in contact with a power line, don’t touch it or try to

remove it yourself. Call your local power company. They will remove it safely.

8. If an accident occurs with the power lines, call for qualified emergency help immediately.

Installation Notes

Antennas transmit and receive radio signals which are susceptible to RF obstructions and common

sources of interference that can reduce throughput and range of the device to which they are connected.

Follow these guidelines to ensure the best possible performance:

•Install the antenna vertically and mount it with the cables pointing towards the ground.

78-20578-01

Installing the Antenna

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

ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid

conduit to lower the antenna away from these obstructions.

•The density of the materials used in a building’s construction determines the number of walls the

signal can pass through and still maintain adequate signal strength. Consider the following before

choosing the location for your antenna:

–

Signals penetrate paper and vinyl walls with little change to signal strength.

–

Signals penetrate only one or two solid and pre-cast concrete walls without degrading signal

strength.

–

Signals penetrate three or four concrete and wood block walls without degrading signal

strength.

–

Signals penetrate five or six walls constructed of drywall or wood without degrading signal

strength.

–

Signals will likely reflect off a thick metal wall and may not penetrate it at all.

–

Signals will likely reflect off a chain link fence or wire mesh spaced between 1 and 1 1/2 in.

(2.5 and 3.8 cm). The fence acts as a harmonic reflector that blocks the signal.

•Install the antenna away from microwave ovens and 2-GHz cordless phones. These products can

cause signal interference because they operate in the same frequency range as the device to which

your antenna is connected.

Choosing a Mounting Location

The antenna should be mounted clear of any obstructions to the sides of the radiating elements.

Generally, the higher an antenna is above the floor, the better it performs. If possible, find a mounting

place directly above your wireless device to ensure the lead-in cable can be as short as possible.

Installing the Antenna

You can install the antenna on any wall. If you intend to install your antenna on another surface, you

must provide the appropriate hardware.

Note Four mounting screws are provided to mount the antenna. To ensure a safe, reliable, and long-standing

installation, you must use all four screws to mount the antenna.

Tools and Equipment Required

A mounting installation kit is shipped with the antenna and consists of the following hardware:

•Four #8 x 1¼ screws

•Four #8 plastic anchors

•Four end caps

You may need the following tools and equipment, which are not provided.

•A Phillips screwdriver

78-20578-01

Installing the Antenna

•A drill

•A #29 (0.136-in. (s.45 mm)) drill bit (for drywall installation, other surfaces may require a different

size).

•A pencil

•A small mallet or hammer

Mounting on a Vertical Surface

Follow these steps to mount your antenna on a vertical surface. This procedure describes mounting the

antenna on a drywall surface. If you are mounting the antenna on any other type of surface, your

procedure may vary slightly.

Step 1 Determine the location where you will mount the antenna.

Step 2 Use the antenna as a template to mark the location of the four mounting holes.

Step 3 Use a drill and #29 drill bit to drill four holes at the locations you marked in Step 2.

Step 4 Start a plastic anchor into each hole.

Step 5 Use a mallet or small hammer to seat the anchors into the wall.

Step 6 Align the antenna’s mounting holes with the anchors.

Step 7 Start a #8 x 1¼ screw into each antenna mounting hole.

Step 8 Use a Phillips screwdriver to secure the antenna to the wall. Do not overtighten.

Step 9 Install the end caps into the antenna mounting holes.

Step 10 Remove the yellow outdoor installation warning label from the antenna radome.

Outdoor Installations

You can mount this antenna outdoors. If you mount the antenna outdoors, you must provide the mounting

hardware. For outdoor installations, follow the instructions printed on the back of the antenna.

Caution An orientation arrow is printed on the back of the antenna that indicates the proper orientation for the

antenna for outdoor installations. You must install the antenna so the arrow points up to prevent any

water intrusion and to provide a drain for any moisture that may accumulate inside the antenna.

Installing the Antenna

Suggested Cable

Cisco recommends a high-quality, low-loss cable for use with the antenna.

Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be

kept as short as possible, because cable length also determines the amount of signal loss (the longer the

run, the greater the loss).
