Sector antenna Ubiquiti PBE-M2-400

The Ubiquiti PBE‑M2‑400 PowerBeam is a high-performance airMAX® bridge and CPE featuring an integrated dish-reflector design for outdoor point-to-point and point-to-multipoint links in the 2.4 GHz band. With InnerFeed® integrated radio technology, the radio is built into the antenna feedhorn to eliminate cable losses and improve overall link performance. The compact form factor provides high antenna gain (18 dBi) while remaining suitable for exposed outdoor installations, with durable construction and a white finish.

Advantages

InnerFeed® integrated radio design removes the need for external RF cabling, reducing signal loss and simplifying installation. The PowerBeam form factor delivers high gain and strong beam directivity for improved performance in noisy environments. airMAX® TDMA-based software enables scalable multipoint networks with high throughput and low latency. The unit is designed for outdoor use and can be mounted with a single wrench for quick pole installation.

Suitable for

• Outdoor point-to-point links in the 2.4 GHz band
• Customer-premises equipment (CPE) for wireless Internet service
• Long-range links where high antenna gain and beam directivity are required
• Installations requiring a compact, weather-resistant antenna

How to use

Assemble the PowerBeam following the included quick-start guide; no special tools are required for assembly and only a single wrench is needed for pole mounting. Connect the device to a PoE injector or compatible network equipment as specified by Ubiquiti, configure airMAX® settings via the device web interface or management software, and align the antenna for optimal signal using signal meters or the software RSSI indicators. Verify link stability and throughput after alignment and secure all mounts and cables against environmental exposure.

Recommendations

Mount the PBE‑M2‑400 with clear line of sight to the remote endpoint and use the integrated alignment tools to minimize interference. Consider the optional PBE‑RAD‑400 radome in particularly exposed locations for added protection.
