AIR-ANT2451V-R is a four-element dual-band Cisco Aironet antenna for indoor coverage. It operates from 2400 to 2500 MHz and 5150 to 5850 MHz, with published peak gain of 2 dBi and 3 dBi respectively.
The horizontal pattern is omnidirectional, so this model is intended to distribute RF energy around the mounting point rather than aim a narrow sector. Cisco documents 80-degree and 50-degree E-plane beamwidths for the 2.4 GHz and 5 GHz elements. Ceiling position, nearby metal and cable loss still require a site survey.
Each element uses an 18-inch plenum-rated cable terminating in a right-angle RP-TNC male connector. Confirm that the selected access point exposes compatible dual-band RP-TNC radio ports; do not assume compatibility from the Aironet brand alone.
Cisco specifies an indoor environment and a 0 to 50 C operating range. This is not a weather-rated outdoor antenna. Check ceiling-tile thickness, mounting clearance and enclosure material before installation.
Inspect all four cables, connectors, radome and mounting hardware. An antenna order does not include an access point, coax extension, lightning protection or a completed RF design.
