Safety Warnings
WARNING: Avoid using or servicing any equipment that has outdoor connections during an electrical storm.
There may be a risk of electric shock from lightning. Statement 1088
WARNING: Do not work on the system, or connect or disconnect cables, during periods of lightning activity. Statement 1001
WARNING: Do not locate the outdoor antenna near overhead power lines or other electric light or power circuits, or where it can
come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits,
as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local
codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada:Canadian Electrical Code, Section 54).
Statement 1052
WARNING: This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available. Statement 1024
WARNING: Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

WARNING: To report a gas leak, do not use a telephone in the vicinity of the leak. Statement 1039
WARNING: This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any
equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing
accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety
warnings that accompanied this device. Statement 1071. SAVE THESE INSTRUCTIONS.
WARNING: This product is not intended to be directly connected to the Cable Distribution System. Additional regulatory
compliance and legal requirements may apply for direct connection to the Cable Distribution System. This product may connect
to the Cable Distribution System ONLY through a device that is approved for direct connection. Statement 1078
Safety Precautions
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!
For your safety, read and follow these safety precautions.
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.
Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the
size and type of antenna that you are about to install.
Find someone to help you—installing an antenna is often a two-person job.
Select your installation site with safety, as well as performance, in mind. Remember that electric power lines and phone
lines look alike. For your safety, assume that any overhead line can kill you.
Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.
Plan your installation carefully and completely before you begin. Each person involved in an installation should be assigned
to 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.
When installing your antenna, follow these guidelines:
— Do not use a metal ladder.
— Do not work on a wet or windy day.
— Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
If the assembly starts to drop, move away from it and let it fall. Because 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.
If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call
your local power company to have it removed safely.
If an accident should occur with the power lines, call for qualified emergency help immediately.

Antenna Installation
The antenna installation includes the following procedures:
Tools and Equipment Required
Installing the Antenna
Tools and Equipment Required
In addition to the parts included in the antenna kit described in the section Antenna Kit, you must provide the following tool to
install the antenna on the router:
A flathead screwdriver
3/4 in. open-end wrench
NOTE: This list does not include the tools and equipment required to assemble and erect the tower, mast, or other structure you
intend to mount your antenna on.
Installing the Antenna
The antenna is provided with a mounting kit consisting of a mounting bracket and hose clamp. This kit allows you to mount the
antenna to masts from 1.25 inches (3.2 centimeters) to 2 inches (5.1 cm). Cisco recommends that a 1.5 inch (3.8 centimeter)
or larger tubing mast be used.
The antenna is vertically polarized. Since the antenna has vertical gain, it is very important to mount the antenna in a vertical
(not leaning) position for optimal performance.
Follow these steps to mount the antenna onto a mast:
1. Place the connector end of the antenna through the hole in the antenna bracket.

should sit lower than aluminum tube)
3. Attach the bracket to the top of the mast. The top surface of the mounting mast must not exceed the top surface of the
mounting bracket. Securely tighten hose clamps.
4. Route the cable to the router and attach the cable to the antenna port of the router.
