Integrated radio design Ubiquiti's InnerFeed technology integrates the radio with the antenna tube, so there is no need for cables to connect the radio with the antenna. This improves performance by eliminating cable losses. Plug and Play installation The PowerBeam does not require any tools to mount, only one wrench is needed for the pole. Amazing Beam antenna performance The shape of the PowerBeam has the highest gain for its size. The excellent orientation of the PowerBeam beam provides the best performance in high noise environments. Advanced software technology Ubiquiti's airMAX technology has proven itself in millions of implementations worldwide, demonstrating exceptional performance in outdoor environments. The TDMA airMAX protocol enables unparalleled scalability, high throughput and low latency in unlicensed, multipoint networks. Protective shield The PBE-RAD-400 is a radio shield that protects the radio from the elements and is available as an optional accessory for the PowerBeam PBE-M2-400. Versatile, highly developed firmware airOS is extremely intuitive and has been designed to require no user training. Behind the user interface there is a powerful, efficient user interface and the firmware architecture enables a efficient, multi-point external network .
