We need to connect two buildings with wlan. Due to the environment we will use AIR-ANT2410Y-R Yagi Antenna. What actual AP (IOS-based) supports this antenna. Is the AIR-SAP2602... the right choice? And how to configure the AP with only one antenna-cable (the 2602 has 4 connectors)
You can use Cisco Aironet access points.
Please refer the link below for more information.
Cisco Aironet 1200 Series and Aironet 1300 Series Access Points supports AIR-ANT2410Y-R Yagi Antenna.
