Cisco Aironet Six-Element Dual-Band
MIMO Patch Array Antenna
(AIR-ANT25137NP-R)
June 3, 2011
This document describes the AIR-ANT25137NP-R antenna and provides
instructions for mounting it. The antenna is a six-element, dual-band,
multiple-input and multiple-output (MIMO), patch array antenna that operates in
the 2.4- and 5-GHz frequency ranges. The antenna is designed for use in indoor
and outdoor environments with Cisco Aironet 3502P Access Points.

Page 9: Choosing A Mounting Location
The fasteners and mounting surface should be capable of maintaining a Note 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.

Page 14: Painting The Antenna
Painting the Antenna Suggested Cable Cisco recommends a high-quality, low-loss cable for use with the antenna. Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. Note 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). - Page 15 Painting the Antenna Figure 5 Vent on Rear of Antenna Cisco Aironet Six-Element Dual-Band MIMO Patch Array Antenna (AIR-ANT25137NP-R) OL-23461-01...
