Ubiquiti Networks AM-5AC21-60 is an airMAX sector antenna designed for use with Rocket radios. This model has a 60° beamwidth, 21dBi gain, and supports 2×2 MIMO.
The airMAX ac Sector Antennas are 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.
Improved Signal-to-Noise Ratio (S/N or SNR), the airMAX ac Sector Antennas allow 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).
