Ubiquiti PBE-M5-400-ISO 2-PACK PowerBeam M5 25dBi ISO 5GHz AirMAX 400mm 25+km Ubiquiti PBE-M5-400-ISO 5 GHz airMAX Bridge with RF Isolated Reflector 2-PACK Incorporating advanced engineering with proprietary airMAX technology, the PowerBeam M5 ISO is ideal for deployments requiring maximum performance and RF isolation. The integrated isolator design improves RF isolation to spatially filter out interference, and the metal-plated interior of the rear housing enhances RF shielding. Ubiquiti airMAX technology is proven in millions of deployments worldwide, exhibiting outstanding performance in outdoor environments. The TDMA airMAX protocol enables unprecedented scalability, high throughput and low latency in unlicensed, multipoint networks. PowerBeam ISO directs RF energy in a tighter beamwidth, and its integrated isolator design improves RF isolation to spatially filter out interference. With its combination of focused beam directivity and RF isolation, the PowerBeam ISO blocks noise to improve noise immunity. This is especially important in an area crowded with other RF signals of the same or similar frequency
