Ubiquiti AM-M521-60-AC: WLAN-AC Sector Ant.

AirMAX ac 2x2 Base Station Sector Antenna, AM-5AC21-60

As the next generation of 2x2 MiMo sector antennas, the airMAX sector antennas feature significant advancements in scalability, noise shielding, and beam performance, complementing the Rocket 5ac radios. They are also compatible with RocketM5 models, although optimal performance requires the Rocket5ac.

Breakthrough Performance
The airMAX ac sector antennas are extremely resilient against disruptive noise in co-location deployments. The innovative deflector design and reduced side and back lobes prevent interference from nearby transmitters—even those on the same tower. An improved signal-to-noise ratio allows for higher modulation, 256QAM instead of 16QAM. This increases bits per second for a fixed bandwidth. Thanks to the innovative design, the airMAX sector antennas provide higher gain and better beam performance for high-capacity multipoint networks.

Market-Leading Isolation Performance
The airMAX ac sector antennas have been designed to enhance noise shielding. When comparing the AM-5AC21-60 pattern to standard antenna patterns, the AM-5AC21-60 offers outstanding noise immunity and beam performance.
