Description

The Cisco AIR-ANT2544V4M-RS is a four-element MIMO dual-band omnidirectional antenna from the Aironet antenna range. It is designed for indoor or outdoor wall or mast mounting with 4x4 Cisco access points that have external RP-TNC antenna connectors, making it a good fit for offices, warehouses and other open areas.

The antenna covers both the 2.4 GHz band (2400-2484 MHz) and the 5 GHz band (5150-5850 MHz), with 4 dBi peak gain on each. All four ports are dual band and terminate in RP-TNC connectors on 3 ft (91.4 cm) plenum-rated cables. Polarisation is linear vertical, with an omnidirectional azimuth pattern and a 60 degree (2.4 GHz) or 33 degree (5 GHz) elevation beamwidth. It operates from -30 to 70 C and needs no power or licence, as it is a passive antenna.

The -RS suffix denotes the Self-Identifying Antenna (SIA) model, which lets a supported access point detect the attached antenna automatically. SIA is supported on Cisco Catalyst 9800 Series Wireless Controllers running IOS-XE 17.4.1 or later, but not on AireOS controllers. The non-SIA sibling is AIR-ANT2544V4M-R.

FAQs

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

Q: Which wireless controllers support the self-identifying (SIA) feature?
A: The -RS model is supported on Cisco Catalyst 9800 Series Wireless Controllers running IOS-XE 17.4.1 or later. It is not supported on AireOS Wireless Controllers.

Q: Which access points does it work with?
A: It is intended for Cisco Aironet and Catalyst access points with dual-band (2.4/5 GHz) RP-TNC external antenna connectors, in 4x4 MIMO configurations.

Q: How does AIR-ANT2544V4M-RS differ from AIR-ANT2544V4M-R?
A: The -RS model adds self-identifying antenna (SIA) circuitry, while the -R model does not. Both are 4 dBi dual-band four-port RP-TNC antennas.

Q: Can it be used outdoors?
A: Yes. It is rated for indoor and outdoor use, with an operating temperature range of -30 to 70 C, and mounts to a wall or mast.
