Mounting on a Pole
To mount your antenna on a pole:
1.
Remove antenna and mount kit from packaging.
2.
Attach antenna mount bracket to the back of the antenna as shown applying a maximum nut-tightening torque of 12 in lbf (1.1 Nm).

6.
Adjust the position of the antenna to the desired azimuth and elevation angles and tighten all pivot hardware (2 places) to a maximum torque of 30 in-lbf (3.4 Nm). The bracket allows the antenna position to be adjustable to +/–45 degrees azimuth and +/–60 degrees elevation.
Note: Cisco recommends grounding the antenna. See Grounding the Antenna.
Mounting on a Vertical Surface
The antenna can be wall mounted. Hardware is not included for wall-mount installation.
To mount your antenna on a vertical surface:
1.
Remove antenna and mount kit from packaging.
2.
Attach antenna mount bracket to the back of the antenna as shown in Attaching Antenna Mount Bracket, applying a maximum nut-tightening torque of 12 in. lbf (1.1 Nm).
3.
Attach elevation adjustable bracket as shown in Attach elevation adjustable bracket and loosely secure hardware.
4.
Using the appropriate customer-supplied anchors and screws, attach the azimuth adjustable bracket to the wall as shown:

Distance Between Bracket Mounting Holes shows, in inches, the distance between the bracket mounting holes.
Figure 7 Distance Between Bracket Mounting Holes
5.
Attach antenna assembly to azimuth bracket, as shown in Attaching Antenna Assembly.
6.
Adjust the position of the antenna to the desired azimuth and elevation angles and tighten all pivot hardware (two places) to a maximum torque of 30 in. lbf (3.4 Nm). The bracket allows the antenna position to be adjustable to +/–45 degrees azimuth and +/–60 degrees elevation.
Note: Cisco recommends grounding the antenna. See Grounding the Antenna.
Antenna Cable Information
The antenna is to be used with the Cisco 1552E access point. The port-to-port designations are as follows: port A of the antenna must be connected to port 4 of the access point, port B of the antenna must be connected to port 6 of the access point, and port C of the antenna must be connected to port 5 of the access point.
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).
Cisco offers low-loss 5 ft. and 10 ft. coaxial cables, parts AIR-CAB005LL-N and AIR-CAB010LL-N, respectively, for connection from the antenna to the access point. These cables have one straight male type-N connector and one right angle male type-N connector. To use all of the ports on the AIR-ANT2588P3M-N three cables will be needed.
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. Silicone sealant or electrical tape are not recommended for sealing outdoor connections.
Grounding the Antenna
Follow these steps to ground the antenna in accordance with national electrical code instructions.
1.
Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires for both mast and lead-in. Securely clamp the wire to the bottom of the mast.
2.
Secure the lead-in wire to an antenna discharge unit and the mast ground wire to the building with stand-off insulators spaced from 4 ft (1.2 m) to 8 ft (2.4 m) apart.
3.
Mount the antenna discharge unit as close as possible to where the lead-in wire enters the building.
4.
Drill a hole in the building’s wall as close as possible to the equipment to which you will connect the lead-in cable.
Caution: There may be wires in the wall. Ensure that your drilling location is clear of obstruction or other hazards.
5.
Pull the cable through the hole and form a drip loop close to where it enters the building.
6.
Thoroughly waterproof the lead-in area.
7.
Install a lightning arrestor.
8.
Connect the lead-in cable to the equipment.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:
■
Reorient or relocate the receiving antenna.
■
Increase the separation between the equipment and receiver.
■
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
■
Consult the dealer or an experienced radio/TV technician for help.
Modifications to this product not authorized by Cisco could void the FCC approval and negate your authority to operate the product.
