Ubiquiti AM-5G20-90 5GHz Sector Antenna

Overview

The Ubiquiti AM-5G20-90 is a 5GHz sector antenna designed for airMAX point-to-multipoint wireless deployments. This antenna delivers 20dBi gain across a 90-degree sector coverage pattern, making it suitable for medium-range coverage areas where directional focus is required. Manufactured in CN and weighing 9.2 lb, the AM-5G20-90 integrates into the UISP Wireless product family, enabling seamless coordination with Ubiquiti's unified wireless management platform.

Key Features

The 90-degree sector form factor provides a balance between coverage width and directional gain, allowing network designers to partition coverage areas with minimal overlap while maintaining substantial signal strength. The 20dBi gain specification delivers adequate range for suburban or semi-rural deployments where base station density can be optimized. The antenna's design facilitates integration with standard airMAX base station equipment, supporting both licensed and license-free 5GHz band operation depending on regional regulatory compliance requirements.

Deployment Scenarios

The AM-5G20-90 performs well in point-to-multipoint topologies where a single base station must serve multiple subscriber locations within a defined azimuth. Typical deployments include fixed wireless access (FWA) networks, rural broadband distribution, and multi-sector base station clusters in urban or campus environments. The 90-degree pattern allows four-sector coverage of a complete 360-degree area with minimal inter-sector interference when properly aligned and spaced.

Network Integration

Within the UISP Wireless ecosystem, the Ubiquiti AM-5G20-90 integrates with airMAX base stations and subscriber modules, leveraging UISP Controller for centralized provisioning, monitoring, and optimization. The antenna supports standard RF connector interfaces common to airMAX equipment, enabling straightforward installation into existing infrastructure.

Installation Notes

At 9.2 lb, the antenna requires appropriate mounting hardware rated for its weight and wind load characteristics. Proper azimuth alignment and elevation adjustment are critical to maximize coverage efficiency and minimize interference with adjacent sectors. Cable runs should be minimized to reduce signal loss, and connectors should be rated for outdoor environmental exposure.

Marty Allison, Infrastructure Architect

"The AM-5G20-90 is a reliable foundation for medium-scale point-to-multipoint networks. Its 20dBi gain and 90-degree pattern offer practical tradeoffs between coverage breadth and range, avoiding the complexity of narrower sectors while maintaining respectable directional focus. Pricing and availability make the Ubiquiti AM-5G20-90 a sound choice for integrators building regional wireless backhauls or last-mile access networks where cost control matters."
