Ubiquiti airMAX 5GHz Horn Antenna (Horn-5)

The Ubiquiti airMAX 5GHz Horn Antenna (Horn-5) is a specialized sector antenna designed to provide precise beam control, superior noise isolation, and efficient coverage for high-performance point-to-multipoint (PtMP) deployments in the 5 GHz frequency range. As part of the airMAX ecosystem, this horn antenna is engineered for seamless integration with Ubiquiti Rocket radios, delivering excellent performance in crowded RF environments or areas requiring tightly controlled signal propagation.

What sets the Horn-5 apart from traditional sector antennas is its symmetrical horn design. Unlike conventional wide-beam antennas, which can introduce interference and signal spillover, the Horn-5 offers a more defined and consistent coverage pattern. With a typical beamwidth of 30° or 45°, depending on the specific model variant, the antenna produces a symmetrical radiation pattern in both the horizontal and vertical planes. This consistent pattern provides predictable coverage and significantly reduces sidelobes and backlobes, helping to isolate signals from neighboring sectors or other RF sources.

Operating in the 5.15 to 5.85 GHz band, the Horn-5 is ideal for deployments in dense urban areas, campus networks, and industrial environments where frequency reuse and interference mitigation are crucial. It supports dual-linear polarization, allowing it to transmit and receive both horizontal and vertical polarizations simultaneously. This improves throughput and link reliability, particularly in environments with multipath propagation.

Constructed for outdoor durability, the Horn-5 features a weather-resistant enclosure that ensures long-lasting performance in challenging environmental conditions. The housing is designed to withstand UV exposure, moisture, and wind, making it a dependable choice for permanent outdoor installations. The compact and lightweight form factor also makes it easier to deploy in space-constrained areas, such as rooftops, utility poles, or crowded tower sites.

Installation is straightforward, thanks to the included precision alignment mount and Rocket radio bracket. This integrated mounting system ensures quick and secure attachment of Rocket radios—such as the Rocket Prism AC—while allowing for precise vertical and horizontal alignment to achieve optimal signal performance. The horn’s stable RF characteristics also enable more consistent throughput and reduced interference, even when multiple antennas are deployed in close proximity.

In summary, the Ubiquiti airMAX 5GHz Horn Antenna (Horn-5) is an advanced RF solution for PtMP networks requiring focused coverage and maximum noise isolation. Its symmetrical beam pattern, superior interference rejection, and easy Rocket integration make it a powerful tool for service providers and system integrators looking to build high-density wireless networks with minimal signal conflict and enhanced spectral efficiency.
