Model: PBE-5AC-400-ISO-US PowerBeam AC ISO          5 GHz airMAX ac Bridge with RF Isolated Reflector The Ubiquiti Networks PowerBeam ac ISO 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. This combination of focused beam directivity and RF isolation, the PowerBeam ac ISO blocks noise to improve noise immunity. Innovative Mechanical Design The integrated isolator design improves RF isolation to spatially filter out interference, and the metal-plated interior of the rear housing enhances RF shielding.
