Cisco Aironet Dual-Band Dipole Antenna - Antenna - 2 dBi, 4 dBi - indoor - grey - for Aironet 3602E

As this access point takes greater advantage of the multiple-input multiple-output (MIMO) features supported under the 802.11n standard, the number of radio transceivers per frequency band has increased. Using dual-band antenna port allows the access point to support these added transceivers while maintaining a reasonably low number of antenna connections.
