The Cisco ANT-MP2-I-OUT-M and ANT-MP2-I-O-SS-M antennas and cable kits are designed to cover frequencies from 698 to 960 MHz and 1710 to 2700 MHz. They are supported on the Cisco CGR 1240 router.
The antennas are designed for direct mounting on the CGR1240 and have an MCX connector.
The Multi-purpose Integrated Antenna features the following:

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 Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
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
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.
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
This section covers the following topics:
This Cisco Multi-purpose Integrated Antenna is designed to be mounted directly onto the router.
In addition to antenna orientation, wireless access point installation location with respect to all wireless clients plays a significant role in determining overall network performance.
Because antennas transmit and receive radio signals, their performance can be adversely affected by the surrounding environment including distance between the Field Area Router (FAR) and cellular base station, physical obstructions, or radio frequency (RF) interference.
Follow these guidelines to ensure the best possible performance:
– Paper and vinyl walls have very little effect on signal penetration.
– Solid and precast concrete walls limit signal penetration to one or two walls without degrading coverage.
– Concrete and wood block walls limit signal penetration to three or four walls.
– A signal can penetrate five or six walls constructed of drywall or wood.
– A thick metal wall or wire-mesh stucco walls causes signals to reflect back and cause poor penetration.
Note If the desired installation site has a marginally acceptable level of radiated noise emissions, consider using a remote-mounted antenna, such as a wall-mount or ceiling-mount antenna, for better radio performance and coverage.
In addition to the parts included in the antenna kit described in the section Integrated Antenna Kits, you must provide the following tool to install the antenna on the router:
For a list of supported ports on the CGR 1240, see Antenna Ports of Chapter 1, “Cisco CGR 1000 and 2000 Series Connected Grid Antennas Overview”.
Follow these steps to install the antenna onto the router:
Step 1 Remove the plug on the antenna connector if one is present.
Step 2 Attach the monopole antenna to your desired antenna port. Do not tighten the antenna completely—stop tightening so that the antenna is not fully installed.
Figure 12-12 Insert Base of Antenna into Router Antenna Port
Step 3 From the chassis interior, the antenna MCX jack should be visible in the plug. With one hand, position the right-angle end of the antenna cable to the antenna’s MCX jack. With your other hand, push the cable end so it inserts into the MCX jack of the antenna.
Step 4 From the exterior of the router, tighten the antenna using the torque wrench. Tighten to 6 to 7 ft-lbs.
Step 5 From the interior of the router, install the coaxial end of the cable to the appropriate connector on your installed module. The antenna and module ports should be the same color (red, yellow, or green). For more information, see Antenna and CG Module Color Codes in Cisco CGR 1000 and 2000 Series Connected Grid Antennas Overview.
Note Some modules require two antennas: a main antenna and a diversity antenna. These modules have two antenna connectors on the front panel, labeled MAIN and DIV. Be sure to connect the main and diversity antennas to the correct module connectors.
