The Ubiquiti PowerBeam AC - PBE-5AC-400 is an airMAX ac Bridge that is ideal for deployments requiring maximum performance and RF isolation. The PowerBeam ac ISO directs RF energy in a tighter beamwidth, and its integrated isolator design improves RF isolation to spatially filter out interference. 
Ubiquiti PowerBeam AC - PBE-5AC-400 Key Features
Frequency - 5 GHz
Gain - 25dBi
Dish Reflector - 400mm
With its combination of focused beam directivity and RF isolation, the PowerBeam ac ISO blocks noise to improve noise immunity. This is especially important in an area crowded with other RF signals of the same or similar frequency.
