Cisco Aironet 3.5-dBi Articulated Dipole Antenna (AIR-ANT5135D-R, AIR-ANT5135DG-R, and AIR-ANT5135DW-R)

.This describes the Cisco Aironet 3.5-dBi articulated dipole antenna, and provides specifications and mounting instructions. The antenna operates in the 5 GHz frequency band and is designed for use with Cisco Aironet 5 GHz radio products using a reverse-polarity TNC (RP-TNC) connector. The three antennas covered in this document are electrically the same. They differ physically by the color of the radome, which is specified by the product part number shown in

System Requirements

This antenna is designed for use with Cisco Aironet access points and bridges, but can be used with any 5 GHz Cisco Aironet radio device that uses RP-TNC connectors.

Features

The antenna has an articulated base that can be rotated 360 degrees at the connection point and from 0 to 90 degrees at its joint. The articulated base is shown in the following illustration.

Installing the Antenna

This antenna operates in the 5 GHz frequency range. Connect this antenna to a 5 GHz antenna connector, which is identified by a blue dot. Connecting this antenna to a 2.4 GHz antenna connector degrades radio performance and could damage the radio.

To install the antenna:

1. Verify that the connector to which you are connecting the antenna is a 5-GHz connector (identified by a blue dot near the access point RP-TNC connector).

2. Align the antenna connector with the RP-TNC connector on the access point.

3. Engage the antenna connector threads with the RP-TNC connector.

4. Tighten the antenna hand tight.

5. Adjust the antenna’s articulated mount to the desired position.

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.
