The Cisco 3G-ANTM1919D antenna operates in the 806- to 960-MHz and 1710- to 2170-MHz frequency bands, and is designed for use with Cisco 3G wireless high speed WAN interface cards (HWICs). The Cisco 3G-ANTM1919D antenna is compatible with the Cisco 3G wireless WAN HWICs using a threaded Neill-Concelman (TNC) male connector with articulating joint.
This antenna has the following features:
•Articulating joint provides 0 to 90 degrees pivot and 180-degree swivel movement, allowing vertical and horizontal orientation of the antenna
•Ground plane independent

The Cisco 3G-ANTM1919D antenna is a remote antenna solution for the Cisco 3G wireless WAN HWICs. The antenna should be connected using the 20-ft or 50-ft cables recommended for this product.
This antenna is designed to be mounted directly to the wireless HWIC. For information about orienting the dipole antenna, see the hardware installation guide for your wireless HWIC.
Caution Do not install this antenna in an outdoor environment.
In addition to the antenna orientation, the installation location of the wireless HWIC plays a significant role in determining overall network performance with respect to all the wireless clients. Clients at the farthest coverage points might have 10 to 50 percent of the bandwidth available to clients close to the antenna. Wireless network coverage in one area or location might need to be lowered to improve the performance for clients in other areas or locations.
Because antennas both transmit and receive radio signals, their performance can be adversely affected by the surrounding environment, including physical obstructions or radio frequency (RF) interference.
Follow these guidelines to ensure the best possible performance:
•Wherever possible, mount the HWIC and antenna where the wireless devices are within sight and without physical obstructions. Barriers along the line of sight between the device and the local base station will degrade the wireless radio signals. HWICs and antennas can be installed above floor level in office environments or near the ceiling for better performance, because most obstructions tend to be near floor level.
•The density of the materials used in a building's construction determines the number of walls the signal must pass through while still maintaining adequate coverage. Consider the following before choosing the location for installing your antenna:
–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 degradation of 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 wall causes signals to reflect back and causes poor penetration.
•Avoid mounting the antenna next to a column or vertical support that could create a shadow zone and reduce the coverage area.
•Keep the antenna away from reflective metal objects such as heating and air-conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use an extension cable to relocate the antenna away from these obstructions.
Caution Install the HWIC and any antennas away from appliances that share the same frequency bands. Microwave ovens, cordless telephones, and security monitors can temporarily interfere with wireless performance.
Caution We recommend avoiding installing wireless antennas in or near rack-mounted equipment that include networking equipment and computer servers whose radiated noise emissions can severely degrade radio performance.
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.
•To extend the coaxial cable included with your antenna, we recomend an ultra-low-loss (ULL) coaxial cable for installation flexibility without a significant loss in range. See Table 2 for a list of ULL information.
Table 2 provides insertion loss information about ULL extension coaxial cables available from Cisco.

Follow these safety instructions when installing your antenna.
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
Warning This equipment must be connected to an indoor antenna only. Statement 373
•Plan your installation procedure carefully and completely before you begin.
•If you are installing an antenna for the first time, for your own safety as well as that of others, seek professional assistance. Consult your dealer, who can explain which mounting method to use for the location where you intend to install the antenna.
•Choose your installation site with both safety and performance in mind. Remember that electric power cables and telephone lines look alike. For your safety, assume that any line is an electric power line until determined otherwise.
•Call your local power company or building maintenance organization if you are unsure about cables close to your mounting location.
•When installing your antenna, do not use a metal ladder. Do dress properly: wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
•If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
