Description

The Aironet AIR-ANT2566D4M-R is a four-port, dual-band directional patch array antenna covering both the 2.4 GHz and 5 GHz Wi-Fi bands. It suits indoor and outdoor deployments where an access point needs four dual-band external antennas, with coverage directed along walls, flat surfaces or masts.

Peak gain is 6 dBi on both bands. The antenna is polarisation-diverse: ports A and C are vertically polarised and ports B and D are horizontally polarised. Connections are four RP-TNC connectors with coupling rings. It covers 2.4-2.5 GHz and 5.15-5.925 GHz, with port-to-port isolation above 30 dB. The standard AIR-ANT2566D4M-R is the non-self-identifying model, so it does not carry the self-identification circuitry of the -RS variant.

The IP-67 rated enclosure operates from -40 to 70 C and withstands winds of 100 MPH. It is a passive antenna and needs no power supply. It is intended for use with approved Cisco Aironet or Catalyst access points that require four dual-band antennas, and an articulating mount allows adjustment in both horizontal and vertical planes.

FAQs

Q: Does this antenna need power?
A: No. It is a passive antenna and needs no power supply or injector.

Q: Which access points does it work with?
A: It is designed for approved Cisco Aironet or Catalyst access points that require four dual-band external antennas, such as the Cisco 2802E.

Q: How does it differ from the AIR-ANT2566D4M-RS?
A: The -RS model adds self-identification for Catalyst 91xx access points and requires a Catalyst 9800 controller running IOS-XE 17.4.1 or later. The -R model does not have this circuitry.

Q: How are the ports polarised?
A: Ports A and C are vertically polarised and ports B and D are horizontally polarised, which gives the polarisation diversity needed for multi-antenna access points.

Q: Is it suitable for outdoor mounting?
A: Yes. The enclosure is IP-67 rated and operates from -40 to 70 C. The articulating mount allows installation on walls, flat surfaces or masts.
