Your Digital Bridge: The PowerBeam M2-400 in Detail
The Ubiquiti PowerBeam M2-400 is more than just an Antenna – it's your reliable solution for demanding Network connections over long distances. As a specialized WiFi Bridge Set, it was developed to establish a stable and fast connection between two locations. Whether you want to connect an IP Camera on a remote part of your property or Network two company buildings, the PowerBeam M2-400 masters this task with flying colors. Thanks to its high directionality, it effectively filters out interference signals from the environment and concentrates all transmitting power exactly where it is needed. The result is an extremely stable connection, even in environments with many other 2.4 GHz Components / wireless networks.
Maximum Efficiency thanks to airMAX and InnerFeed™ Technology
Ubiquiti relies on two key technologies for the PowerBeam that set it apart from the competition. InnerFeed™ technology integrates the radio unit directly into the Antenna's feedhorn. This eliminates susceptible Antenna Cables that could lead to signal loss. Every millimeter of power arrives where it belongs. Additionally, the proprietary airMAX TDMA protocol revolutionizes data transmission. Instead of the chaotic CSMA method of standard WiFi Routers, airMAX assigns fixed time slots to each client. This prevents data collisions, reduces latency, and ensures consistently high data throughput – crucial for professional Point-to-Point (PtP) connections.
Built to Last: Robustness for Outdoor Use
A device for outdoor use must withstand extreme conditions. The PowerBeam M2-400 is designed precisely for this. The housing is made of UV-stabilized plastic that will not become brittle even after years in the sun. The included pole mount and fasteners are provided with a GEOMET coating to effectively prevent corrosion. With a wind survivability of over 200 km/h and an operating temperature range of -40°C to 70°C, you can rely on your connection remaining stable in wind and weather. Configuration via the intuitive airOS web interface makes setup straightforward even for advanced users.

Frequently Asked Questions (FAQ)
Can I use the PowerBeam M2-400 as a regular WiFi Access Point for my home?
No, the PowerBeam M2-400 is unsuitable for this. It is a highly directional antenna designed for point-to-point or point-to-multipoint connections over long distances. Its signal is strongly focused and not intended for broad area coverage of a room or garden. For home use, dedicated WiFi Antennas or WiFi Access Points are more suitable.
What is the difference between the PowerBeam M2-400 and a 5 GHz model like the PBE-M5-400?
The main difference lies in the frequency band. The PBE-M2-400 operates in the 2.4 GHz band, which offers better penetration of obstacles but is often more susceptible to interference from other Network devices. 5 GHz models, part of 5 GHz Components, potentially offer higher speeds and less interference, but require an even clearer line of sight. Both are crucial for optimizing your Network.
Do I need two PowerBeam M2-400 for a connection?
Yes, for a classic Point-to-Point (PtP) wireless bridge to connect two buildings, you need two identical devices that are precisely aligned with each other. This forms a reliable WiFi Bridge Set. In a Point-to-Multipoint (PtMP) Network, the PowerBeam acts as a Client (CPE) that connects to a central base station.
What does 'airMAX TDMA Protocol' mean?
airMAX is Ubiquiti's proprietary technology that replaces the standard WiFi protocol. It uses Time Division Multiple Access (TDMA) to assign fixed transmit and receive times to each client. This prevents data collisions and ensures higher stability, lower latency, and better throughput across the Network, a key feature of Ubiquiti Networks products.
How is the PowerBeam M2-400 powered?
Power is supplied exclusively via the included 24V Passive Power over Ethernet (PoE) adapter. This means that power and data are transmitted to the device via a single Ethernet Cable, which significantly simplifies outdoor installation and reduces the need for separate power supplies. This is a common feature for PoE Injectors / Power Supplies.
Is the configuration suitable for beginners?
Configuration is done via the airOS web interface and requires basic Network understanding. While the user interface is considered intuitive, correctly configuring a stable wireless bridge is more suitable for advanced users or after familiarization with the subject matter.
