Cisco Aironet 2.4 GHz and 5 GHz
Dual-Band Polarization-Diverse Directional
Array Antenna (AIR-ANT2566D4M-R)
This document describes the Cisco Aironet 2.4 GHz and 5 GHz Dual-Band Polarization-Diverse Directional Array Antenna
(AIR-ANT2566D4M-R), and provides electrical specifications and mounting instructions.
The AIR-ANT2566D4M-R antenna is a four-port polarization-diverse array that operates over the 2.4 GHz and 5 GHz Wi-Fi
bands. It ships with an articulating mount for use on flat surfaces and masts, and is adjustable in both horizontal and vertical
planes. The radome can be painted using commonly available non-conductive spray paints, such as Krylon or Rust-Oleum.
The antenna is designed for use in indoor and outdoor environments with an approved Cisco Aironet access point that requires
four dual-band antennas.
