Antenna Configurations; Low Profile Dual-Band 2.4/5-Ghz Omni Antenna Array - Cisco Aironet 1550 Installation Manual

Chapter 1 Overview

Antenna Configurations

The 1552 access point supports a variety of antennas designed for outdoor use with radios operating in
the 2.4-GHz and 5-GHz frequency bands. In addition to an integrated antenna array, the 1552 supports
the external antennas listed in the following sections.
Two mounting configurations are available, the cable strand mount and the pole mount (refer to
"Mounting the Access Point" section on page
Using an optional antenna mounting bracket kit, the directional antennas AIR-ANT2413P2M-N and
AIR-ANT5114P2M-N can be mounted directly on an access point in a strand mount or pole mount
environment. The antenna bracket kit contains four bracket sections and fasteners that you can assemble
in multiple configurations to position and aim the directional antenna in a range of positions. For more
information on mounting the antenna with the optional mounting bracket, refer to Installing
Directional-Antenna Mounting Kits on Cisco 1550 Series Outdoor Mesh Access Points.
The AIR-CAP1552E-x-K9 model must always be operated with the three external antennas attached.

shows the antenna port locations for model 1552E.
Contains an array of three dual-band omni antennas—The three omni antennas are contained within
this single radome, which greatly reduces the antenna's visual footprint and reduces the possibility
of snagging the antenna on the cable bundle, the RF cable, or test cables.
Operates over both 2.4 GHz and 5 GHz bands—Each of the three omni antennas is a dual-band
antenna, covering both the 2.4–2.5 GHz band, and the 5.2–5.9 GHz bands.
Gain of about 2 dBi at 2.4 GHz, 4 dBi at 5 GHz.
Cisco Light Gray weatherproof radome for outdoor operation.
