AIR-ANT2451NV-R Overview
AIR-ANT2451NV-R Low-Profile Ceiling Antenna
AIR-ANT2451NV-R is Cisco's six-element, dual-band MIMO omnidirectional antenna for indoor ceiling deployment. Its 2400-2500 MHz and 5150-5850 MHz coverage is different from a single-band or directional patch antenna.
Six-element RF layout
Cisco publishes 2.5 dBi peak gain at 2.4 GHz and 3.5 dBi at 5 GHz. The azimuth pattern is omnidirectional, while the elevation beamwidth is 63 degrees at 2.4 GHz and 55 degrees at 5 GHz. Mounting height and building attenuation must be included in the RF plan.
Low-profile installation details
The radome is 8.6 inches in diameter and 1.8 inches thick. Its three-foot plenum-rated cables terminate in RP-TNC plugs; Cisco marks the 5 GHz leads in blue. Verify lead identification and AP port mapping before commissioning MIMO chains.
Environmental limit
The official guide states indoor-only use with an operating range of 0 to 55 C. The ceiling format does not provide outdoor weather protection, so it should not be substituted for an exterior antenna.
Receiving and compatibility
Confirm six undamaged leads, intact connectors and the required mounting parts. Match frequency support, connector type and radio-chain count to the exact access point model before ordering.
