Ubiquiti airMAX Sector Antenna 900MHz 13dBi 120° (AM-9M13-120)

The Ubiquiti airMAX Sector Antenna 900MHz 13dBi 120° (AM-9M13-120) is a specialized sector antenna engineered to deliver extended range, superior penetration, and broad sector coverage in the sub-GHz 900 MHz frequency band. Designed specifically for rural or non-line-of-sight (NLOS) applications, this antenna offers an ideal solution for Wireless Internet Service Providers (WISPs) or enterprise operators looking to deploy broadband services across difficult terrain or heavily obstructed environments. The 900 MHz band is particularly effective at penetrating foliage, buildings, and other obstructions, making this antenna perfect for rural broadband and agricultural monitoring applications.

Operating in the 902 to 928 MHz ISM band, the AM-9M13-120 offers a solid 13 dBi of gain and a wide 120° horizontal beamwidth, providing strong sector coverage with excellent signal reach. This wide beam enables the antenna to serve a large area with a single access point, reducing the need for multiple towers or antennas and thus lowering deployment costs. Additionally, the antenna features dual-linear polarization for both vertical and horizontal signals, ensuring better signal clarity and robustness, especially in challenging NLOS conditions.

One of the standout features of the AM-9M13-120 is its ability to work in concert with Ubiquiti’s Rocket M900 radio. The antenna includes an integrated Rocket mounting bracket, which allows for quick, secure, and tool-free installation of the Rocket M900 radio unit. This seamless integration ensures consistent alignment, optimal signal propagation, and simplified deployment in the field.

The AM-9M13-120 is built to withstand demanding outdoor environments. Its rugged construction includes a weather-resistant enclosure that protects internal components from moisture, UV radiation, and environmental wear. This robust build quality ensures reliable long-term operation in a wide range of climates and conditions. The antenna also includes a precision mounting bracket that facilitates secure pole-mount installations and allows for easy vertical tilt adjustments to fine-tune signal coverage during setup.

By delivering a high front-to-back ratio and superior cross-polarization isolation, the antenna effectively minimizes interference from adjacent sectors and external RF sources. This ensures clean, high-throughput communication, even in areas with overlapping wireless networks. The result is improved spectral efficiency and overall network performance.

In summary, the Ubiquiti airMAX Sector Antenna 900MHz 13dBi 120° (AM-9M13-120) is a powerful, purpose-built solution for extending broadband coverage in NLOS and rural environments. With its wide beamwidth, durable construction, and exceptional performance in the 900 MHz band, it enables efficient and reliable connectivity in locations where traditional wireless frequencies fall short.
