The 4G-ANTM-OM-CM antenna requires a Cisco 3G EHWIC that uses a TNC-Male connector.
This antenna is designed to be mounted indoors on a ceiling. The antenna is mountable to ceiling tiles less than 1" thick or to hard ceilings with the included installation accessories.
Follow these guidelines to ensure the best possible performance:
Note The antenna must be mounted to a ceiling to maximize its omnidirectional propagation characteristics. Mounting it on a wall may noticeably decrease the antenna range and overall performance.
•Wherever possible, mount the EHWIC and antenna where the wireless devices would be within sight and avoid physical obstructions. Barriers along the line of sight between antenna and EHWIC degrades the wireless radio signals.
•The density of the materials used in a building's construction determines the number of walls the signal must pass through and still maintain adequate coverage. Consider the following before choosing the location to install 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 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.
•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 EHWIC 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 you avoid installing wireless antennas in or near rack-mounted installations that include networking equipment and computer servers whose radiated noise emissions can severely degrade radio performance.
Follow these safety instructions when installing your antenna:
•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 safety as well as 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: 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.
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 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 Do not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool. Statement 1035
Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. Statement 1036
Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Statement 1037
Warning To report a gas leak, do not use a telephone in the vicinity of the leak. Statement 1039
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, because 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 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.

Step 1 Drill a 3/4" diameter hole in the ceiling where you want to mount the antenna.
Step 2 (Optional) Drill three pilot holes and insert the supplied screw anchors.
Note You can secure the antenna in place using only the mounting nut. However, for additional support, you can also use the supplied mounting screws. To use the mounting screws, you must first drill three pilot holes and insert the supplied screw anchors in place.
a. Insert the antenna's cable and thread through the hole you drilled in Step 1 until the base of the antenna is flush with the ceiling.
a. Using a pencil or pen, mark the screw positions on the ceiling.
b. Remove the antenna from the ceiling.
c. Using a 3/16" drill bit, drill three holes for the screw anchors.
d. Properly insert the three screw anchors into the pilot holes.
Step 3 Insert the antenna's cable and thread through the hole you drilled in Step 1 until the base of the antenna is flush with the ceiling.
Step 4 From above the ceiling:
a. Thread the supplied flat washer through the antenna's cable and thread.
b. Thread the supplied spring washer through the antenna's cable and thread.
c. Thread the supplied mounting nut through the antenna's cable.
d. Attach the mounting nut to the antenna's thread by manually turning the nut clockwise until the antenna is secured in place.
Step 5 (Optional) Insert the mounting screws, then cover them with the white screw covers.
Step 6 Connect the antenna's cable to one of the supported extension cables.
To extend the coaxial cable included with your antenna, we recommend an ultra-low-loss coaxial cable for installation flexibility without a significant loss in range. The following table lists insertion loss information about ULL extension coaxial cables available from Cisco.
