Improved Noise Immunity The PowerBeam directs RF energy in a tighter beamwidth. With the focus in one direction, the PowerBeam blocks or spatially filters out noise, so noise immunity is improved. This feature is especially important in an area crowded with other RF signals of the same or similar frequency. Innovative Mechanical Design Built-in mechanical tilt The mounting bracket conveniently offers 20° of uptilt and up to 20° of downtilt. Quick assembly The number of fasteners was reduced to simplify assembly. Tools are required only when the technician mounts the PowerBeam on the pole. Easy removal The antenna feed can be detached with the push of a button. Corrosion Resistance Fasteners GEOMET®-coated for improved corrosion resistance when compared with zinc-plated fasteners. https://www.ubnt.com/airmax/powerbeam/ airMAX (Fixed Outdoor Wireless)
