This section describes the technical specifications and installation instructions for the Cisco Dual Port, Dual Band Outdoor Vehicle Mount and Fixed Infrastructure WLAN Antenna, hereafter referred to as the antenna. The antenna is a dual-port antenna designed to cover 2.4 GHz and 5 GHz WLAN bands. The antenna can be mounted on the roof of a vehicle or fixed structure. The antenna meets or exceeds a variety of environmental ruggedization specifications for transportation applications.

Caution

Read all the safety information before installing or replacing antennas.

The antenna features:

• 2.4 and 5 GHz dual band support
• Omnidirectional, vertically polarized, 2x2 MIMO
• Outdoor and transportation ready
• Roof mount installation
• Integrated 3 foot long LMR-240 cables with RP-TNC plug connectors
• The two WiFi elements are interchangeable.

This section contains the following:

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

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

In order to comply with FCC radio frequency (RF) exposure limits, antennas should be located at a minimum of 7.9 inches (20 cm) or more from the body of all persons. Statement 332

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.

Warning

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.
