Ubiquiti (PBE-M5-300) PowerBeam 22dBi AirMax Wireless Bridge

The Ubiquiti PowerBeam M5-300 (PBE-M5-300) is a high-performance, outdoor 5 GHz wireless bridge engineered to establish long-range, high-throughput Point-to-Point (PtP) or Point-to-MultiPoint (PtMP) network links. Ideal for wireless internet service providers (WISPs), industrial facility interconnections, and remote CCTV backhauls, this device integrates a high-gain 22 dBi directional dish antenna with a proprietary RF transmitter core.

By leveraging Ubiquiti’s advanced airMAX technology and InnerFeed design—which embeds the entire radio directly into the antenna’s feedhorn—it eliminates external cable connection losses to deliver exceptional signal integrity. Operating on the clean, less congested 5 GHz frequency band, the PBE-M5-300 serves as a robust, cost-effective solution for bridging distant local networks without the massive expense of trenching structural fiber lines.

Key Features

• High-Gain 22 dBi Antenna: Utilizes a highly directive 300mm parabolic reflector dish that tightly focuses RF energy into a narrow beam, drastically minimizing noise interference from neighboring wireless networks.

• Innovative InnerFeed Technology: Couples the radio transceiver core directly to the antenna feedhorn assembly, discarding the need for external RF jumper cables and preventing signal attenuation loss.

• Proprietary airMAX TDMA Protocol: Implements Time Division Multiple Access (TDMA) scheduling to prevent wireless node collisions, maximizing airtime efficiency and delivering high throughput over long distances.

• Over 150 Mbps Real Throughput: Features a high-capacity internal hardware architecture ($560\text{ MHz}$ Atheros processor and $64\text{ MB}$ DDR2 RAM) capable of pumping real TCP/IP data rates exceeding 150 Mbps.

• Long-Range Link Range Profile: Designed with high output transmission power and exceptional receiver sensitivity, comfortably stabilizing wireless data links across distances of 15+ kilometers (9+ miles).

• Intuitive airOS Configuration Engine: Controlled via a fully functional web-based network management system packed with advanced diagnostic utilities, real-time constellation graphs, and an automated site survey tool.

• All-Weather Outdoor Durability: Built inside a ruggedized, UV-stabilized polymer and powder-coated steel casing rated to endure extreme outdoor temperatures (-40°C to 70°C) and buffeting hurricane winds up to 125 mph.

• Passive Power over Ethernet (PoE): Operates cleanly using a single standard Ethernet cable to transfer both high-speed data and 24V DC operating power, simplifying tower and roof pole deployments.

• Advanced ESD/Surge Protection: Incorporates built-in, multi-kilovolt electro-static discharge (ESD) isolation circuitry to safeguard the internal mainboard from nearby lightning strikes and environmental grid surges.

• Fluid 3-Axis Adjustment Bracket: Features an innovative rear mounting assembly that lets field technicians easily adjust pan, tilt, and elevation tracking for perfect link alignment.

Conclusion

The Ubiquiti PowerBeam M5-300 22dBi airMAX Wireless Bridge stands as an exceptional, carrier-class networking utility for deploying rock-solid, long-distance outdoor data paths. By unifying high-gain directional beam tracking, integrated cable-free radio engineering, and smart TDMA channel scheduling into a compact parabolic layout, it ensures data integrity remains pristine across miles of open air. Its tough, outdoor-hardened build and easy pole-mounting installation make it an incredibly reliable and budget-friendly choice for deploying remote building-to-building network expansions.
