This antenna is designed for use with CW-ACC-GPS1 accessory module.

Note	The model CW-ANT-GPS1-M-00 is supported only on Cisco Catalyst 9800 Series Wireless Controllers running an IOS-XE 17.4.1 release or a later release. This antenna model is not supported on Cisco AireOS Wireless Controllers.

Warning

Do not locate the 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 (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280

For your safety, read and follow these safety precautions.

1. 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.

2. Find someone to help you—installing an antenna is often a two-person job.

3. 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.

4. Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.

5. 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.

6. When installing your antenna, follow these guidelines:

   1. Do not use a metal ladder.

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

   3. Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.

7. 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.

8. 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.

9. If an accident should occur with the power lines, call for qualified emergency help immediately.

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.

• 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.

  • Signals may be blocked by Low-E (Low-Emissivity or Low-Emittance) glass windows or solar control films applied to windows.

• 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.

You can install the antenna outdoors or indoors depending on the country, on any flat vertical surface. All hardware for mounting the antenna indoors or outdoors is provided. If you intend to install your antenna on another surface, you must provide the appropriate hardware.

Important

To ensure regulatory compliance, the surge protection attachment is required for use of the antenna outside of the USA or Canada.

You must use the provided surge protection attachment when:

• Installing the antenna outdoors (in the US or Canada)

• Installing the antenna indoors or outdoors outside of the USA or Canada.

Use the MMCX connector and the provided 32.80-ft. (10 m) plenum cable to connct the antenna to the AP.
