Ubiquiti PowerBeam M5 300 ISO (PBE-M5-300-ISO)

The Ubiquiti PowerBeam M5 300 ISO (PBE-M5-300-ISO) is a compact, high-isolation airMAX CPE (Customer Premises Equipment) designed to deliver superior wireless performance in point-to-point (PtP) and point-to-multipoint (PtMP) applications. Operating in the 5 GHz frequency band, it offers a powerful combination of advanced RF design and directional isolation to enhance throughput, reduce interference, and ensure consistent network performance in dense or noisy environments.

At the core of the PBE-M5-300-ISO is Ubiquiti’s integrated radio design, which eliminates the need for coaxial cables, minimizing signal loss and maximizing power efficiency. The device delivers up to 150+ Mbps real TCP/IP throughput and features an integrated 22 dBi antenna with a narrow beamwidth. This focused transmission pattern reduces noise interference from nearby radios, making it highly effective in RF-congested deployments or urban installations.

The distinguishing feature of the “ISO” model is the addition of an RF isolation shield that surrounds the antenna feed. This shielding improves the antenna's front-to-back ratio and enhances signal isolation from surrounding devices operating in the same frequency range. The result is stronger, cleaner links with minimal interference and reduced cross-talk between co-located radios—an essential feature for service providers deploying multiple devices on a single tower or rooftop.

Built with Ubiquiti’s proprietary airMAX TDMA protocol, the PBE-M5-300-ISO increases scalability and reduces latency, making it ideal for high-performance outdoor deployments. The device also supports intelligent QoS (Quality of Service), ensuring prioritization of voice and video traffic while maintaining reliable data transmission. This makes it a great fit for ISPs offering VoIP, video streaming, or other real-time services.

The PBE-M5-300-ISO features a lightweight yet durable enclosure that is designed for outdoor durability. Its all-in-one mechanical design simplifies installation, requiring fewer components and no specialized tools. The device mounts easily on poles and provides adjustable azimuth and elevation for precise antenna alignment.

Network administrators can manage the unit using Ubiquiti’s intuitive airOS software, which provides powerful tools for signal analysis, RF configuration, and firmware upgrades. For centralized network visibility and monitoring, the device also integrates seamlessly with Ubiquiti’s UNMS (UISP) platform.

In summary, the Ubiquiti PowerBeam M5 300 ISO (PBE-M5-300-ISO) is a reliable and high-isolation CPE designed for performance-critical wireless deployments. Its integrated design, directional beam, RF shielding, and airMAX technology make it an excellent solution for service providers and integrators looking to deliver robust wireless connectivity in challenging RF environments.
