Overview
The Ubiquiti PBE-M5-300-ISO-US is a PowerBeam M5 300 ISO 5 GHz airMAX bridge featuring a 300 mm RF-isolated reflector. The integrated RF isolation design helps spatially filter interference, while the directional antenna provides 22 dBi gain for point-to-point and other fixed wireless deployments.
Wireless Performance
The PBE-M5-300-ISO-US operates in the US 5 GHz frequency range of 5725–5850 MHz. It supports 5, 8, 10, 20, 30, and 40 MHz channel sizes and uses dual-linear polarization. Ubiquiti specifies maximum throughput of 150+ Mbps and antenna gain of 22 dBi.
Key Features
- 300 mm RF-isolated reflector for improved RF isolation
- 22 dBi directional antenna gain
- 150+ Mbps maximum throughput
- 5–40 MHz channel bandwidth support
- Integrated airMAX technology for outdoor wireless networking
RF Isolation and Deployment
The integrated isolator design is intended to reduce the impact of surrounding RF interference by spatially filtering unwanted signals. The directional PowerBeam reflector is suitable for fixed wireless links where focused coverage and antenna isolation are required.
Networking and Power
The bridge provides one 10/100 Ethernet port and uses passive two-pair PoE. A 24 V, 0.5 A PoE adapter is included. The supported voltage range is 20–27 V DC and maximum power consumption is 6 W.
Mechanical and Environmental Specifications
The PBE-M5-300-ISO-US measures 364 × 364 × 276 mm and weighs 2.6 kg. The outdoor UV-stabilized polycarbonate enclosure is designed for pole mounting, with the pole-mount kit included. Operating temperature is -40°C to 70°C with 5–95% non-condensing humidity.
DC Supplies Product Note
The ISO designation is significant: this model uses the 300 mm RF-isolated reflector rather than the standard PowerBeam M5 300 reflector. The US variant is specified for 5725–5850 MHz, so the exact regional model should be used when regulatory frequency requirements matter.
