The AIR-ANT3213 is a Pillar Mount Diversity Omni Antenna that is used indoors and has unobtrusive medium range. Access Point Antennas are compatible with all Cisco RP-TNC-equipped access points. The antennas are available with different gain and range capabilities, beam widths, and form factors. Coupling the right antenna with the right access point allows for efficient coverage in any facility, as well as better reliability at higher data rates. This antenna is an intelligent system of two antennas that continually senses incoming radio signals and automatically selects the antenna best positioned to receive it.
