Ubiquiti AM-5G19-120 5GHz Sector Antenna

Overview

The Ubiquiti AM-5G19-120 is a 5GHz airMAX sector antenna engineered for point-to-multipoint wireless deployments in carrier-grade networks. This sector antenna delivers 19 dBi gain across a 120-degree horizontal coverage pattern, making it well-suited for mid-to-long-range base station applications where coverage density and directional focus are critical. Weighing 9.6 pounds and manufactured in China, the unit integrates seamlessly into Ubiquiti's UISP Wireless product family, providing a cost-effective foundation for expanding outdoor mesh and fixed wireless networks.

Key Features

The AM-5G19-120 operates in the 5 GHz frequency band with a 19 dBi gain rating, concentrating RF energy across a 120-degree sector pattern. This configuration balances coverage breadth with directional efficiency, reducing interference in moderately populated deployment zones. The antenna's sector form factor is optimized for basestation mounting on towers and poles, where elevation and azimuth placement can be fine-tuned independently. The robust construction supports outdoor installation in variable climates, and the moderate weight (9.6 lb) simplifies mounting hardware requirements and reduces structural load on support infrastructure.

Deployment Scenarios

The AM-5G19-120 is deployed as a base station antenna in point-to-multipoint networks covering suburban and semi-rural service areas. Common use cases include wireless ISP (WISP) networks, enterprise campus backhaul, and municipal broadband infrastructure. The 120-degree pattern allows a single tower to support three coordinated sectors covering 360 degrees, or partial coverage in asymmetric deployment topologies. In UISP-integrated networks, multiple AM-5G19-120 units operating on the same or adjacent towers enable frequency reuse schemes that maximize spectrum efficiency.

Network Integration

The Ubiquiti AM-5G19-120 pairs with compatible 5 GHz airMAX radios and basestation equipment within the UISP Wireless ecosystem. Integration requires standard RF cable runs and mounting brackets; impedance matching and connector compatibility with your radio platform must be verified during design. The antenna's sector pattern is passive—no electrical tuning is required. Network management occurs at the radio and controller level using UISP or UniFi software, allowing centralized monitoring and optimization of antenna-level performance metrics.

Installation Notes

Mount the AM-5G19-120 at tower or pole height appropriate to your coverage objectives, ensuring ground clearance and line-of-sight to subscriber locations. Secure the antenna with standard U-bolt and mast-mounting kits rated for the 9.6 lb weight plus wind loading. Cable runs should be low-loss LMR-400 or equivalent, with proper grounding and surge suppression at the radio interface. Azimuth orientation and vertical tilt are adjusted mechanically during installation; careful alignment is essential for optimal sector coverage and interference mitigation. Allow adequate clearance from other antennas to minimize inter-system coupling.
