Chapter 2 Installing the Access Point
Installing Antennas
dipole antennas is a dual-band antenna, covering both the 2.4 - 2.483 GHz band and the 5.25-5.85 GHz
bands. The antenna have a peak gain of about 3 dBi at 2.4 GHz and 5 dBi at 5 GHz. The antenna unit is
gray weatherproof radome for outdoor operations.
External Antenna Mounting Configurations
The selection of the antenna is determined in the configuration of the product. The 1572E antennas can
be mounted on a wall, pole and/or tower mounted. Please refer to the

the 2.4-GHz and 5-GHz frequency bands. The 1572 supports the external antennas listed in the following
sections.
Cisco Aironet Dual-Band Omnidirectional Antenna (AIR-ANT2547V-N, AIR-ANT2547VG-N)
The Dual-Band Omnidirectional Antenna, referred to as a “stick” antenna, is designed for outdoor use
with Cisco Aironet Outdoor Access Points with radios operating in the 2.4-GHz and 5-GHz frequency
bands (
Figure 2-16
). Basic operating features of the antenna are:
•
Omnidirectional colinear array
•
Operates in the 2.4 GHz and 5 GHz frequency bands
•
Gain:
–
2400–2483 MHz — 4-dBi
–
5250–5875 MHz — 7-dBi
The antenna is designed to create an omnidirectional broadcast pattern. To achieve this pattern, mount
the access point clear of any obstructions to the sides of the radiating element.
