Full Product Overview : Ubiquiti PBE-M5-400 PowerBeam M5 Outdoor Antenna
The Ubiquiti PBE-M5-400 is part of Ubiquiti’s PowerBeam series, designed specifically for long-range point-to-point and point-to-multipoint connections. It operates on the 5 GHz frequency band, which is preferred for outdoor wireless setups due to its cleaner spectrum compared to the crowded 2.4 GHz range. The integrated dish antenna provides a gain of 25 dBi, enabling it to deliver stable links even in challenging environments with high interference.
This model is built around Ubiquiti’s proprietary airMAX technology, which uses TDMA (Time Division Multiple Access) to maximize throughput and minimize latency. With a throughput capacity of up to 150+ Mbps real TCP/IP throughput, the PBE-M5-400 M5 Outdoor Antenna is well-suited for bandwidth-hungry applications like video streaming, IP CCTV backhaul, and data transmission between sites. The device is powered through 24V passive PoE, which simplifies deployment by allowing both data and power to travel over a single Ethernet cable.
Detailed Design and Build
One of the highlights of this device is its solid construction. The 400 mm reflector dish is made of durable material designed to withstand harsh outdoor conditions including wind, rain, and extreme temperatures. Ubiquiti’s design philosophy focuses on minimizing RF leakage and maximizing signal directionality — this means that most of the energy is concentrated in one direction, resulting in better performance and less interference with other radios in the area.
The mounting system is another strong point of the Ubiquiti PBE-M5-400 M5 Outdoor Antenna. It is easy to assemble, with a dish-to-feedhorn alignment that doesn’t require special tools. The precision alignment bracket ensures that installation is quick and stable, even on towers or poles.
Applications of Ubiquiti PBE-M5-400
The Ubiquiti PBE-M5-400 M5 Outdoor Antenna is versatile and used in many scenarios:
- Point-to-Point Links: Ideal for connecting two distant buildings with high-speed internet where running fiber is too expensive.
- Wireless Backhaul: ISPs use it to connect remote relay towers or distribute internet to rural areas.
- Video Surveillance Networks: Perfect for transporting CCTV traffic from remote camera locations back to a central monitoring station.
- Temporary or Emergency Networks: Quick to deploy for events, disaster recovery, or temporary construction sites where wired links are not available.
Ports and Connectivity
Despite being a wireless bridge, port availability still matters. The PBE-M5-400 features:
- 1x 10/100 Ethernet Port: This is the main data and PoE input port, allowing both power and network traffic through a single cable.
- PoE Support: Works with 24V passive PoE injector (included in the box) for flexible power delivery.
- Reset Button: Hidden but accessible for device recovery or quick configuration resets.
For most installations, this single Ethernet port is all you need because the PowerBeam acts as a dedicated wireless bridge.
Aligning Your PBE-M5-400 for Best Performance
Proper alignment is key for getting the most out of your Ubiquiti PBE-M5-400 M5 Outdoor Antenna. Use Ubiquiti’s airView spectrum analyzer and built-in alignment tools within the web interface to find the clearest channel. Make small incremental adjustments while monitoring signal strength (RSSI) and noise floor. The goal is to maximize SNR (Signal-to-Noise Ratio) for the cleanest link.
Securing Your Wireless Link
Because the PBE-M5-400 is often used for critical infrastructure, enabling WPA2-AES encryption is a must. Combine this with proper VLAN segmentation and firewall rules at the network level. Ubiquiti’s airMAX firmware allows you to lock down the device so only authorized stations can connect, reducing the risk of unauthorized access.
