The Ubiquiti PBE-2AC-400 PowerBeam AC Outdoor 2.4GHz 18dBi WiFi 5 Point-to-Point Link is ideal for CPE deployments requiring maximum performance. It directs RF energy in a tighter beamwidth, and with the focus in one direction the PowerBeam 2AC 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.
