Overview of the 4G-LTE-ANTM-O-3-B Antenna
Deciding which antenna to use involves multiple factors, such as coverage area, maximum distance, indoor location, outdoor location, and antenna height.
When an antenna is used indoors, the building construction, ceiling height, and internal obstructions must be considered. In outdoor environments, obstructions such as trees, vehicles, buildings, and hills must be considered. Distance is the primary factor when using outdoor-wireless communications. However, coverage area also becomes important when you use wireless client devices to communicate with a wireless device.
4G-LTE-ANTM-O-3-B antenna is an integrated 3-in-1- indoor and outdoor antenna. It comes with two Long Term Evolution (LTE) antennas and one Global Positioning System (GPS) antenna in a single radome. 4G-LTE-ANTM-O-3 Antenna shows the 4G-LTE-ANTM-O-3 antenna.

Safety Precautions
This section contains the following warning statements. A warning means danger. You are in a situation that could cause bodily injury. Before working on an equipment, be aware of the hazards involved with electrical circuitry and standard safety practices to prevent accidents.
Statement 1052—Installing and Grounding the Antenna
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, refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada:Canadian Electrical Code, Section 54).
Statement 1024—Ground Conductor
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 1025—Use Copper Conductors Only
Warning : Use copper conductors only.
Statement 1046—Installing or Replacing the Unit
Warning : When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Caution : For your physical safety, and to help you install your antenna successfully, 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 of 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 and 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.
Installation Instructions
The following section contains steps for installing the 4G-LTE-ANTM-O-3-B antenna:
1.
While choosing the location, keep the following in mind:
–
Attempt to center the antenna on a flat plane.
–
Attempt to position the antenna so that it has 8 inches of flat plane in any given direction.
–
Attempt to space at least 16 inches from an adjacent antenna or metallic structure and choose a location with gentle surface curves to ensure proper sealing.
–
Ensure that there is a space that is 2 inches deep and 2 inches in diameter below the mounting surface to allow sufficient clearance for the mounting stud, hardware, and cables.
–
Ensure that the diameter of the hole is 5/8 inch.
2.
Drill a hole through the mounting surface where the center of the antenna is located, as shown in Drill the Mounting Surface.
Note : Ensure that the hole is deburred of sharp edges to prevent cable damage during installation.
Figure 10 Drill the Mounting Surface
3.
Clean the mounting surface around the hole. The surface must be free of any debris, which would otherwise prevent the antenna's inner foam gasket from adhering to or the outer rubber gasket from forming a seal.
4.
Remove the nut from the mounting stud and cables one by one.
5.
Insert the mounting stud through the hole and then thread the cables through the serrated face nut one by one.
Warning : It is important that the orientation of the serrated face nut should be correct. Otherwise, the serrated part of the lock nut will not bite into the mounting stud.

6.
Position the antenna onto the mounting surface and tighten the nut hand-tight, as shown in Tighten the Nut after the Antenna is fully seated. Tighten it further using a wrench until the antenna is fully seated. Visually inspect the outer rubber antenna gasket to ensure that it has been compressed and sealed tightly against the mounting surface and radome.
Figure 12 Tighten the Nut after the Antenna is fully seated
Deployment Scenarios
Deployment of an Antenna with One Router shows the deployment of the 4G-LTE-ANTM-O-3-B antenna on an ATM with a single router.
Note : All the three antenna cables are SubMiniature version A (SMA-male) connectors, but the MAIN and the Diversity (DIV) of the router has the Threaded Neill–Concelman (TNC-female) connectors, and the GPS has an SMA-female connector. In this case, an SMA-female to TNC-male adapter needs to be used to connect the SMA-male connectors to the MAIN and DIV of the router because they cannot be connected to the SMA-male connectors directly.
Figure 13 Deployment of an Antenna with One Router
Deployment of an Antenna with Dual Routers shows the deployment of 4G-LTE-ANTM-O-3-B on an ATM with dual routers.
