Step 2 Use the articulated mount base as a template to mark the locations of the four mounting holes. Step 4 Start a plastic wall anchor into each hole. Step 5 Use a mallet or small hammer to seat the wall anchors into the wall. Step 6 Align the articulated mount base's mounting holes with the anchors. Figure 2 shows, in inches, the distance between the bracket mounting holes. Step 7 Start a self-tapping screw into each antenna mounting hole.
Step 8 Use a Phillips screwdriver to secure the articulated mount base to the wall. Do not overtighten. Step 9 Complete the assembly of the other parts as described beginning in step 3 of the following section. The antenna is mounted on an articulated mounting device as shown in Figure 3. The articulated mount is used to provide a way to adjust the antenna elevation and azimuth through a limited range. Figure 3 shows the articulated mount installed on a pole.
You can also install it on any suitable flat surface, as mentioned in the previous section. Step 1 Place hose clamps around the pole and the articulated mount base as shown. Step 2 Position the mounting plate on the pole in the direction the antenna should face and tighten the hose clamp with a screwdriver.
Step 3 Use the azimuth adjustment bolt, nut, and washers to install the knuckle assembly on the articulated mount base. Tighten the screw finger tight. Step 4 Use the elevation adjustment bolt to attach the antenna mounting plate and antenna to the knuckle assembly. Step 5 Use the azimuth and elevation adjustments to fine tune the antenna's azimuth and elevation.
Step 6 When the antenna is properly adjusted, use a flat-head screwdriver to tighten the azimuth and elevation adjustment screws. Step 7 Route the antenna cable to the wireless device. Note Cisco recommends grounding the antenna. See the "Grounding the Antenna" section for details. Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. Because cable length also determines the amount of signal loss, the cable should be kept as short as possible the longer the run, the greater the loss.
The antenna terminates with an N-connector after a short, 1-ft The mating connector to the antenna is an appropriate N-connector jack. The connector on the opposite end will vary according to the type of equipment used. After the cable is attached to the antenna, make sure that the connections are sealed if outdoors to prevent moisture and other weathering elements from affecting performance.
Cisco recommends using a coax seal such as CoaxSeal for outdoor connections. Silicon sealant or electrical tape are not recommended for sealing outdoor connections.
Follow these steps to ground the antenna in accordance with national electrical code instructions. Step 1 Use No. Securely clamp the wire to the bottom of the mast. Step 3 Secure the mast ground wire to the building with stand-off insulators spaced from 4 ft 1.
Step 4 Mount the antenna discharge unit as closely as possible to where the lead-in wire enters the building. Step 5 Drill a hole in the building's wall as closely as possible to the equipment to which you will connect the lead-in cable.
Step 6 Pull the cable through the hole and form a drip loop close to where it enters the building. Step 7 Thoroughly waterproof the lead-in area. Comes with two in. Suitable for use on Aironet and mesh access points. Suitable for use on Cisco Aironet and Series mesh access points. Has an N-type connector and will require a separate low-loss cable for mounting to the access point. Articulating mount included. Fits mast poles with a maximum diameter of 2 in. Suitable for use on Aironet outdoor access points.

The following information is provided in this document:. 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, read and follow these safety precautions. They may save your life! Your Cisco sales representative can explain which mounting method to use for the size and type of antenna you are about to install. Remember that electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
Tell them your plans and ask them to come and look at your proposed installation. This is a small inconvenience considering your life is at stake. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned 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. Remember, 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: You! Call your local power company. They will remove it safely. For a listing of all the warning statements and their translations, see Translated Safety Warnings for Cisco Aironet Access Points at:.
Antennas transmit and receive radio signals that are susceptible to RF obstructions and common sources of interference that can reduce throughput and the range of the device to which they are connected. Follow these guidelines to ensure the best possible performance:.
If necessary, use a rigid conduit to lower the antenna away from these obstructions. Consider the following before choosing the location for your antenna:. The fence acts as a harmonic reflector that blocks the signal. These products can cause signal interference because they operate in the same frequency range as the device to which your antenna is connected. Figure 1 Contents of the Antenna Bracket Kit. Four are included in the kit. Two are included in the kit.
M8 stainless steel serrated washer. Mounting flanges required for installation. The dimensions noted in the following illustrations are all in mm, unless noted otherwise. Figure 2 Dimensions of the Antenna with Brackets and Cables. You can install the antenna on a wall or ceiling must be a flat surface , or on a pole with a minimum diameter of 2 inches 5. The antenna should be mounted clear of any obstructions to the side or front of the enclosure, which contains the radiating elements.
Keep in mind that this antenna should be aimed at the intended coverage area. Therefore, you should mount the antenna such that the desired mechanical tilt is achieved. If possible, mount the antenna near the access point so that you can use the shortest possible connecting cables.
Before you start with mounting the antenna, go through the mounting procedure for each kind of installation and ensure that you have all tools and fasteners mentioned therein ready. The following is a general list of fasteners and tools which are not included in the antenna and brackets kit. Note The fasteners and mounting surface should be capable of maintaining a minimum pullout force of pounds 68 kg to support the weight of the antenna along with the potential wind loading on the antenna.
The articulating mount flange bracket. Figure 6 Cable Restraint on the Back of the Antenna. Cable restraint. Figure 8 Azimuth Adjustment. Figure 9 Elevation Adjustment. For the recommended cable type, see the Recommended Cable. Note The pole or mast must be rigid enough to hold the weight of an antenna along with 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.
One of the two required articulating mount flange brackets come attached to the back of the antenna see Contents of the Antenna Bracket Kit. The other flange bracket, included in the kit, is the one used in this step. You can use the azimuth and elevation markings on the articulating mounting arm and the flange brackets as a guide.
