Ubiquiti’s PBE-218, PowerBeam M, has a compact, all-in-one design with uniform beam width, efficient footprint and a faster processor. The PowerBeam can be easily mounted in a variety of ways thanks to the innovative mechanical design.This high-performance airMAX® Bridge directs RF energy in a tighter beam-width. 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.
