Ubiquiti airMAX RocketDish AC - 31dBi


Key Features


  • Integrated mount for Rocket

  • 2x2 MIMO 5.8GHz

  • Designed specifically for airMAX Rocket M5.




  • The RocketDish RD-5G31-AC is a 2X2 MIMO dish antenna designed to seamlessly integrate with RocketM radios (RocketM sold separately)

  • Pair the RocketM’s radio with the RocketDish antenna’s reach to create the endpoint of a high-performance, Point-to-Point (PtP) backhaul

  • We regularly deploy RocketDish M5s as the high bandwidth backbone between two sites, typically out to 15km (rLOS). In shorter range communications smaller form-factor equipment can be deployed, but this can leave the link susceptible to interference and reduced throughput due to link adaptation

  • Another concern is channel pollution (observed as a rise in noisefloor at other APs/stations), particularly when the transmitter is tower or rooftop mounted

  • While Ubiquiti spec this antenna at 31dBi, in real world terms 0.6m dishes have around 27-28dBi gain. If your link requires ~30dBi gain antennas, please check out our 0.9m antennas:


Here is one example of how the RocketDish can be deployed.



  • The Ubiquiti Research and Development team engineered the RocketDish RD-5G31-AC with high isolation and Front-to-Back (F/B) ratio - the main benefit is improved Signal-to-Noise Ratio (S/N or SNR).

  • The improved F/B ratio and lower sidelobes reduce the interference from other transmitters in the area – potentially on the same tower

  • The improved S/N ratio allows a higher-order modulation to be used, for example, 256QAM rather than 16QAM. This in turn increases the number of bits per second for a fixed bandwidth, which is also known as the data rate.
