The Ubiquiti PowerBeam M5 400mm (Model: PBE-M5-400) specification description follows:
The Ubiquiti PowerBeam M5 400mm (Model: PBE-M5-400) is a high-performance airMAX Wireless Bridge purpose-built for long-range Point-to-Point (PtP) links and Point-to-MultiPoint (PtMP) CPE deployments. Operating in the 5 GHz frequency band, the device integrates InnerFeed technology with a 400 mm parabolic dish reflector to deliver 25 dBi antenna gain, superior directional beamwidth, and optimal noise immunity across challenging RF environments.
Powered by airOS software and a high-speed Atheros processor, the PBE-M5-400 delivers real TCP/IP throughput exceeding 150+ Mbps with exceptional link range reaching over 25+ km. Featuring a UV-stabilized plastic enclosure with a geomet-coated mechanical bracket, it incorporates a Gigabit Ethernet interface, 24V Passive PoE support, and precision pole-mounting alignment controls for quick, robust outdoor installation.
Comprehensive Key Features:
Integrated InnerFeed Technology: Integrates the radio directly into the antenna feed horn, eliminating coaxial cable losses and maximizing RF efficiency.
High Gain Parabolic Reflector: Features a 400 mm dish reflector delivering 25 dBi gain with tight beam directivity for long-distance wireless links.
High Noise Immunity: Directs RF energy in a tighter beamwidth to reject co-location noise and improve signal quality in crowded spectrums.
Advanced airOS Operating System: Built-in airOS software supporting airMAX TDMA protocol, real-time airView spectrum analysis, and advanced network diagnostic tools.
Gigabit Ethernet Performance: Equipped with a 10/100/1000 Mbps RJ45 port to prevent wired throughput bottlenecks on high-speed wireless links.
Tool-Free Ball-Joint Assembly: Designed for rapid field assembly and precise 3-axis alignment using a heavy-duty pole-mounting bracket.
Durable Outdoor Construction: GEOMET-coated fasteners and powder-coated steel mounting components provide enhanced corrosion resistance against severe outdoor environments.
