As the next generation of 2×2 MIMO sector antennas from Ubiquiti Networks, the airMAX® ac Sector Antennas feature significant advances in scalability, noise isolation, and beam performance to complement the Rocket™5ac radios.

They are also compatible with RocketM5 models; however, optimal performance requires the Rocket5ac.

The airMAX ac Sector Antennas are highly resistant to noise interference in co-location deployments. The innovative deflector design, together with the reduced sidelobes and backlobes, reject interference from other transmitters in the area – potentially on the same tower.

Improved Signal‑to-Noise Ratio (S/N or SNR) 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).

Due to innovative design, the airMAX ac Sector Antennas provide higher gain and superior beam performance for high‑capacity, multipoint networks.


Breakthrough Design and Performance
The airMAX® ac Sector Antennas feature carrier-class construction with an innovative deflector design and 2×2, dual-polarity performance for airMAX networks.



Superior Noise Immunity
Featuring reduced sidelobes and backlobes, the airMAX® ac Sector Antennas are engineered to reject noise interference in co‑location deployments.
Market-Leading Beam Performance
Compare the diagram of the airMAX® ac Sector Antenna, model AM-5AC22-45, to the diagram of a standard sector antenna, and note the superior noise immunity and beam performance of the AM-5AC22-45.


Industrial-Strength Construction
airMAX® ac Antennas are designed with robust mechanical design for outdoor application use.
Plug and Play Integration
Every airMAX® ac Antenna has a built-in Rocket™ mount, so no tools are needed to install the Rocket BaseStation.
