The AIR-ANT2588P3M-N is the Cisco Aironet 2.4-GHz/5-GHz 8-dBi directional antenna: a 3-port antenna with N-connectors that operates in both the 2.4 GHz and 5 GHz bands and is made for outdoor use. It is a 3-element dual-polarized patch antenna with a peak gain of 8 dBi in both bands.
The operating frequency ranges are 2400 to 2500 MHz and 5150 to 5900 MHz, with 50 ohm nominal input impedance and a VSWR of 2:1 or less. Polarization is linear and dual. The elevation plane 3 dB beamwidth is 30 degrees and the azimuth plane 3 dB beamwidth is 120 degrees. Sidelobe level is below -20 dBc and the front-to-back ratio is above 10 dB.
There are three N-female bulkhead connectors. The antenna measures 12 in. long, 7 in. wide and 1.1 in. high (30.48 x 17.78 x 2.79 cm), weighs 16 oz (0.45 kg) and has an IP67 environment rating. It is used outdoors with any Cisco Aironet access point that requires three dual-band antennas.
For RF exposure limits, other antennas than dish antennas should be placed at least 7.9 inches (20 cm) from the bodies of all persons, and the antenna must be grounded and kept away from overhead power lines during installation. A four-port Aironet relative is the AIR-ANT2513P4M-N four-port dual-band patch array antenna, and more antennas are in Cisco wireless.
