Overview
The Ubiquiti PBE-M5-400 is an airMAX PowerBeam M5 400 designed for 5 GHz wireless point-to-point and bridge deployments. It combines a 400 mm reflector with 25 dBi antenna gain and an integrated airMAX radio to provide a directional wireless link with 150+ Mbps throughput. The unit includes a Gigabit Ethernet interface, passive PoE power, pole mounting hardware, and an outdoor UV-stabilized enclosure.
5 GHz airMAX Wireless Bridge
The PBE-M5-400 operates in the 5 GHz band and is designed for directional wireless networking. Ubiquiti specifies a worldwide supported frequency range of 5170–5875 MHz, with the applicable frequency range depending on the deployment region and local regulatory requirements.
25 dBi Directional Antenna
The 400 mm reflector provides 25 dBi antenna gain for focused wireless transmission and reception. The directional design is suited to point-to-point bridge links where the two endpoints can be aligned with each other.
Gigabit Ethernet and Passive PoE
The PBE-M5-400 provides one Gigabit Ethernet RJ45 port for network connectivity and uses 2-pair passive PoE for power. Ubiquiti specifies a 24V, 0.5A Gigabit PoE adapter for the device, with a supported input voltage range of 20–27V DC and maximum power consumption of 8W.
Outdoor Construction
The enclosure uses UV-stabilized polycarbonate and is designed for outdoor operation. The unit is specified for an operating temperature range of -40°C to 70°C and 5–95% non-condensing humidity.
Wind Resistance and Mounting
A pole mounting system is included with the PBE-M5-400. The antenna has a specified wind survivability of 200 km/h (125 mph) and a wind loading of 342.5 N at 200 km/h.
Installation Considerations
The PBE-M5-400 is intended for professional installation. Ubiquiti specifies the use of shielded Ethernet cabling and earth grounding for the radio installation, while operation must comply with applicable local frequency, output-power, and DFS requirements.
Key Features
- 5 GHz airMAX wireless bridge with 25 dBi antenna gain
