Features:

The airMAX® 802.11ac Sector Antenna is a 2x2 MIMO sector antenna from Ubiquiti Networks that features significant advances in scalability, noise isolation, and beam performance to complement the Rocket™ 5ac radios.
The airMAX 802.11ac Sector Antenna is highly resistant to noise interference in co-location deployments and feature an innovative deflector design, together with the reduced sidelobes and backlobes, reject interference from other transmitters in the area – potentially on the same tower.
With improved Signal-to-Noise Ratio (S/N or SNR), the airMAX 802.11ac Sector Antenna allows a higher-order modulation to be used, for example, 256QAM rather than 16QAM. This increases the number of bits per second for a fixed bandwidth (or data rate).

Specification:

The airMAX ac Sector Antennas feature significant advances in scalability, noise isolation and beam performance to complement the Rocket5ac radios in Point-to-MultiPoint (PtMP) networks. They are compatible with RocketM5 models; however, optimal performance requires the Rocket5ac.
