Integrated Radio Design
The Ubiquiti’s InnerFeed® technology integrates the radio into the feedhorn antenna, so it does not need a radio connecting cable to the antenna. This increases performance because it eliminates cable loss.
Plug and Play installation
PowerBeam ™ does not require special tools to assemble it; only a screwdriver to attach the mounting.
Outstanding “Beam” Antenna Performance
The form factor of PowerBeam ™ gives the highest gain for its size. PowerBeam directs the directed beam that is amazing and provides the best performance even at high noise.
Powerful airOS® feature
The versatile Ubiquiti airOS® firmware technology enables high-performance, outdoor multi-point networks. AirOS provides features such as wireless settings, bridging or routing and configuration management system services.
Advanced Software Technology
AirMAX® Ubiquiti technology is proven in millions of installations throughout the world, demonstrating outstanding performance in the outdoor environment. The TDMA Airmax protocol allows unprecedented scalability, high and low latency throughput, and multipoint networks.
Radome Protector
PBE-RAD-400 is a protective radome that protects the radio from certain elements, such as wind. This accessory is optional for PowerBeam PBE-M2-400 and PBE-M5-400, sold separately.
