Cisco Aironet Four-Port Dual-Band Polarization-Diverse Array Antenna (AIR-ANT2513P4M-N)
This document describes the AIR-ANT2513P4M-N antenna and provides electrical specifications and mounting instructions. The antenna is a four-port polarization-diverse patch array that operates over the 2.4-GHz and 5-GHz Wi-Fi bands. It ships with an articulating mount for use on flat surfaces and masts and is adjustable in both the horizontal and vertical planes. The radome is paintable using commonly available non-conductive spray paints, such as Krylon or Rust-Oleum. The antenna is designed for use in indoor and outdoor environments with Cisco Aironet 3702P and 1570 series access points.
Warning IMPORTANT SAFETY
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
- 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 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.
- Select 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.
Because antennas transmit and receive radio signals, they 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:
- Mount the antenna to utilize its propagation characteristics. This antenna is designed to radiate energy in a somewhat narrow beam from the front of the antenna. It should be aimed into the intended coverage area.
- 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 must pass through and still maintain adequate coverage. Consider the following before choosing the location to install your antenna:
The antenna should be mounted clear of any obstructions to the side or front of the enclosure. Keep in mind that this antenna should be aimed into the intended coverage area, so you should mount the antenna so that the desired mechanical tilt can be achieved. If possible, mount the antenna near the access point so you can use the shortest possible connecting cables.
You can install the antenna on any flat surface or on a pole with a minimum diameter of 2 inches (5.08 cm) and a maximum diameter of 5 inches (12.7 cm). The antenna and one mounting flange are connected together when shipped. When mounting the antenna you need to assemble the bracket hardware, connect the antenna and bracket to the mounting surface, and adjust the antenna orientation.
Figure 4 shows the parts included with the antenna bracket.
Note The fasteners and mounting surface should be capable of maintaining a minimum pullout force of 150 pounds (68 kg) to support the weight of the antenna and bracket plus the potential wind loading on the antenna.
Note The pole or mast must be rigid enough to hold the weight of the antenna plus the associated forces produced by wind loads. In addition, the pole or mast must be structurally strong enough to withstand the clamping force of the hose clamps.
Note The fasteners and mounting surface should be capable of maintaining a minimum pullout force of 150 pounds (68 kg) to support the weight of the antenna plus the potential wind loading on the antenna.
Step 3 Attach the mounting bracket to the wall or ceiling using four screws or bolts and anchors through the holes on the bracket. Figure 5 shows the wall-mount bracket.
Step 4 Assemble the bracket hardware as shown in Figure 6.
Step 5 Make sure you orient the antenna correctly (note the arrow on the back of the antenna that indicates the top of the antenna). Use a 1/2 in. (13-mm) wrench to loosen the elevation adjustment bolt and the elevation pivot bolt.
Step 6 Adjust the azimuth (side-to-side position) and elevation (up-and-down position) of the antenna. Loosen the adjustment bolts slightly to allow for adjustment. Azimuth angle can be adjusted ±25 degrees and elevation can be adjusted ±60 degrees. You can use the azimuth and elevation markings on the mounting arm and the wall flange as a guide.
See the Suggested Cable section for cable recommendations.
Note The pole or mast must be rigid enough to hold the weight of the antenna plus the associated forces produced by wind loads. In addition, the mast must be structurally strong enough to withstand the clamping force of the hose clamps.
Step 1 Follow steps 1 and 2 from the Mounting on a Wall or Ceiling section.
Step 2 Position and mount the mounting flange (Figure 4) onto the pole or mast using the hose clamps provided in the kit. The hose clamps should pass through the slots on the mounting flange (Figure 5).
Step 4 Assemble the antenna and bracket to the flange as shown in Figure 6.
Step 9 Connect the antenna cables to the access point. The antenna ports are labeled A through D, from left to right. Connect the antenna port A to connector A on the access point, antenna port B to connector B on the access point, and so on. See the Suggested Cable section for cable recommendations.
Cisco recommends a high-quality, low-loss cable for use with the antenna, such as Cisco AIR-CAB005LL-R-N= (5 ft low-loss cable with RP-TNC and N-type connectors) for AP3702P, or AIR-CAB005LL-N= or AIR-CAB010LL-N= (5 ft and 10 ft N-type connectors, respectively) for AP1570. Four cables are required.
Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
Painting the antenna and the bracket does not affect its performance if you use standard exterior-grade, oil-based or latex paint. Do not use metallic or metallic-flake paints, which will degrade antenna performance.
Note Before painting the antenna, cover the pressure-release vent on the rear, lower-left of the antenna with masking tape to prevent clogging (Figure 3).
