Κατευθυντική κεραία Ubiquiti PBE-5AC-500 27 dBi, 5 GHz

The Ubiquiti PowerBeam™ ac PBE-5AC-500 is a high‑gain directional antenna for the 5 GHz band, offering 27 dBi of gain in a compact dish form factor. It integrates the radio with the antenna feed using InnerFeed® technology to eliminate cable losses and includes a protective radome to shield the radio from harsh outdoor conditions. The unit supports airMAX® ac features for improved throughput, latency, and noise immunity and is suitable for CPE and point‑to‑multipoint installations.

Advantages

The integrated InnerFeed® design removes the need for a separate radio-to-antenna cable, reducing signal loss. airMAX® ac and a custom airMAX® engine deliver improved latency, scalability and higher throughput compared with earlier generations. The PowerBeam™ ac offers high beam directivity and excellent gain for its size, providing better performance in noisy outdoor environments. A protective radome increases durability for outdoor deployments.

Suitable for

• CPE (Customer Premises Equipment) for fixed wireless links
• Point-to-multipoint links in unlicensed 5 GHz networks
• Long-range directional links requiring high gain and narrow beamwidth
• Environments with elevated radio noise where beam directivity improves performance

How to use

Mount the PowerBeam™ ac on a suitable mast or pole with a clear line of sight to the remote station. Align the dish carefully toward the target location to maximise signal strength; the antenna’s high directivity requires precise aiming. Connect power and network according to the Ubiquiti installation guide and configure airMAX® settings via the device management interface to match your network topology and channel plan. Ensure the radome faces the expected weather exposure and that mounting hardware is tightened to manufacturer torque specifications.

Recommendations

For best results, use the PowerBeam™ ac in point‑to‑multipoint networks with coordinated channel assignment and appropriate sector planning. Regularly inspect the radome and mounting for corrosion or mechanical loosening, and verify firmware updates from Ubiquiti to maintain optimal performance and security.
