This section describes the technical specifications and installation instructions for the Cisco Cellular 3-in-1 Vehicle Mount and Fixed Infrastructure Antenna, hereafter referred to as the antenna. The antenna is a three port antenna with two elements designed to cover the 698-960, 1448-1511 and 1710-2700 MHz cellular bands and one GPS element. 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.

Note	Read the information in the safety section before installing or replacing antennas.

The antenna features:

• Three antenna elements within one radome: two cellular and one GPS
• Outdoor and transportation ready
• Roof mount installation
• Dual cellular elements supporting 698-960, 1448-1511 and 1710-2700 MHz
  • Omnidirectional, vertically polarized, MIMO
  • Integrated 2 foot cables with TNC male connectors
  • LTE elements are interchangeable, either one can be connected to Main or Aux
• Active GPS antenna has integrated 17 foot cable with SMA male connector

The antenna may require RF extension cables. A shorter 2 foot cable length was selected on LTE WAN to allow you to optimize LTE WAN performance and wireless range. If you require a cable length longer than 2 feet with the antenna, then select RF extension cables of appropriate length and type.

Thicker RF cables, such as LMR-600, LMR-400, or LMR-240 result in lower loss, higher RF performance and longer range of wireless network than thinner cables such as LMR-195, LMR-200. The trade-off is that thicker cables are more difficult to bend and route.

For optimal performance, the length of thin cables needs to be kept as short as possible. For example, 2 foot and 10 foot lengths of LMR-195 cable at 2700 MHz frequency would have losses of 0.5dB and 2.3dB respectively. In this example at 2700 MHz the area covered by the wireless system with the 10 foot cable is reduced by 34% compared to 2 foot cable. Radius of communication is degraded by 20% in 10 foot vs 2 foot case.

The following tables detail the antenna’s specifications.

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.
