Ubiquiti NanoBeam 2AC 2.4GHz 500mW Radio with 13dBi Antenna. Ubiquiti Networks launches the latest generation of airMAX CPE (Customer Premises Equipment), the NanoBeam® 2AC with dedicated Wi-Fi management. The NanoBeam 2AC directs RF energy in a tighter beamwidth. With the focus in one direction, the NanoBeam 2AC blocks or spatially filters out noise, so noise immunity is improved. This feature is especially important in an area crowded with other RF signals of the same or similar frequency. The radio and antenna are combined to create a more efficient and compact CPE. The NanoBeam 2AC gets maximum gain out of the smallest footprint. Providing high performance and an innovative form factor, the NanoBeam 2AC is versatile and cost-effective to deploy.
