Description

The Cisco Aironet AIR-ANT2566D4M-RS is a wall-mount, dual-band polarization-diverse directional patch array antenna covering 2.4 GHz and 5 GHz. It suits indoor and outdoor wall-mounted directional coverage with external-antenna Aironet and Catalyst access points that need four dual-band antennas. The -RS variant adds self-identification circuitry so Catalyst 91xx access points can detect the antenna automatically.

The antenna delivers 6 dBi peak gain on both bands across four MIMO ports (A to D), all dual-band. Ports A and C are vertically polarised and ports B and D are horizontally polarised, with port-to-port isolation above 30 dB. Connections are made through four RP-TNC connectors with coupling rings on 3 ft leads. The housing is IP-67 rated and operates from -40 C to 70 C, with a 100 MPH operational wind rating.

It is designed for access points with dual-band external antenna ports, such as the Aironet 1830, 1850, 2800 and 3800 Series and Catalyst 9115AX, 9120AX and 9130AX. The Self-ID function is supported with Cisco Catalyst 9800 Series Wireless Controllers running IOS-XE 17.4.1 or later. The antenna is passive and needs no power or licence.

FAQs

Q: Does this antenna need a licence or power?
A: No. It is a passive antenna, so it needs no power and no licence.

Q: Which controllers support the Self-ID function?
A: The -RS model is supported with Cisco Catalyst 9800 Series Wireless Controllers running IOS-XE 17.4.1 or later. It is not supported on AireOS controllers.

Q: Which access points does it work with?
A: It suits access points with dual-band external antenna ports, such as the Aironet 1830, 1850, 2800 and 3800 Series and Catalyst 9115AX, 9120AX and 9130AX.

Q: How does the -RS differ from the AIR-ANT2566D4M-R?
A: The -RS adds self-identification circuitry that Catalyst 91xx access points recognise automatically. The -R version has no Self-ID and can be used with AireOS.

Q: Can it be used outdoors?
A: Yes. The antenna is IP-67 rated and operates from -40 C to 70 C, so it suits indoor and outdoor wall-mounted use.
