Overview
The Ubiquiti PBE-M5-300-ISO-RSO is a 5 GHz airMAX PowerBeam bridge designed for outdoor point-to-point wireless networking. It combines a 300 mm RF-isolated reflector with an integrated 5 GHz radio and 22 dBi antenna gain to provide a directional wireless link.
Wireless Connectivity
The PowerBeam M5 300 ISO operates across the 5 GHz frequency range specified for the model and supports channel widths of 5, 8, 10, 20, 30, and 40 MHz. Its dual-linear polarization and directional reflector are designed for point-to-point wireless bridge deployments.
Ubiquiti specifies throughput of 150+ Mbps for the PowerBeam M5 300 ISO. Actual wireless performance depends on channel conditions, configuration, interference, distance, regulatory limits, and the characteristics of the connected equipment.
RF-Isolated Reflector
The 300 mm RF-isolated reflector is a defining feature of this PowerBeam variant. With the reflector installed, the unit provides directional outdoor coverage. Ubiquiti also documents operation without the reflector using the 3 dBi antenna feed for outdoor-to-indoor coverage.
Networking and Power
The device provides one 10/100 Ethernet port for network connectivity and power delivery. It uses passive PoE with pairs 4, 5+ and 7, 8 return, and the specified 24V, 0.5A PoE adapter is included.
Outdoor Installation
The enclosure uses UV-stabilized outdoor plastic and is designed for pole mounting. The unit is specified for operation from -40°C to 70°C and 5% to 95% non-condensing humidity. Ubiquiti specifies wind survivability of 200 km/h (125 mph) for the PowerBeam M5 300 ISO.
Key Features
- 5 GHz airMAX outdoor wireless bridge with 22 dBi antenna gain
- 300 mm RF-isolated reflector for directional wireless operation
- Supports 5/8/10/20/30/40 MHz channel widths
- 10/100 Ethernet interface with passive PoE power
- Pole-mounting hardware and 24V, 0.5A PoE adapter included
Applications
The PBE-M5-300-ISO-RSO is suited to outdoor point-to-point wireless links where directional 5 GHz connectivity is required. It can be deployed as part of an airMAX wireless bridge between compatible network locations, with the reflector providing the directional RF configuration documented by Ubiquiti.
DC Supplies Product Note
The PBE-M5-300-ISO-RSO should be planned as a 10/100 Ethernet and passive-PoE device rather than a Gigabit Ethernet bridge. Ubiquiti specifies a 24V, 0.5A PoE adapter and a maximum power consumption of 6W. For outdoor installation, shielded Category 5 or higher Ethernet cabling is recommended by the manufacturer and should be grounded through the PoE adapter's AC ground.

FAQs
What is the PBE-M5-300-ISO-RSO?
It is a Ubiquiti airMAX PowerBeam M5 300 ISO outdoor 5 GHz wireless bridge with a 300 mm RF-isolated reflector and 22 dBi antenna gain.
What Ethernet speed does the PowerBeam M5 300 ISO support?
The unit has one 10/100 Ethernet port. It is therefore not a Gigabit Ethernet interface.
What frequency does the device use?
The PowerBeam M5 300 ISO operates in the 5 GHz band. Ubiquiti specifies a worldwide frequency range of 5150–5875 MHz, subject to the applicable regulatory domain.
What PoE adapter is required?
Ubiquiti specifies a 24V, 0.5A PoE adapter and uses passive PoE over two pairs. The PoE adapter is included with the product.
Can the reflector be removed?
Yes. Ubiquiti documents operation without the reflector using the 3 dBi antenna feed for outdoor-to-indoor coverage. The reflector is used for the directional outdoor configuration.
Is mounting hardware included?
Ubiquiti specifies a pole-mounting kit as included with the PowerBeam M5 300 ISO.
