Ubiquiti AM-5G16-120 5GHz Sector Antenna

Overview

The Ubiquiti AM-5G16-120 is a sector antenna designed for point-to-multipoint airMAX deployments across the 5GHz band. This antenna is engineered as part of the UISP Wireless product family, delivering 16dBi gain with a 120-degree horizontal beamwidth suitable for wide-coverage base station applications. Manufactured in China and weighing just 0.100 lb, the AM-5G16-120 integrates easily into existing Ubiquiti infrastructure and pairs with compatible airMAX basestation hardware to extend wireless coverage across urban, suburban, and rural service areas.

Key Features

The sector antenna's 16dBi gain rating provides sufficient signal amplification for mid-range point-to-multipoint links while the 120-degree coverage pattern balances range with angular coverage—ideal for basestation installations where broad sector coverage is required. The compact form factor and lightweight construction at 0.100 lb simplify mounting and reduce structural load on tower installations. The AM-5G16-120 operates within the standard 5GHz airMAX frequency bands and integrates directly with Ubiquiti airMAX devices including basestation radios and access points.

Deployment Scenarios

This antenna is well-suited for mesh backbone links, ISP point-to-multipoint networks, and enterprise campus connectivity where a single basestation must serve multiple subscriber locations within a defined geographic sector. The 120-degree beamwidth makes it effective in grid-pattern deployments where multiple sectors cover a service area without excessive overlap. It is also appropriate for temporary or semi-permanent wireless infrastructure where quick deployment and repositioning are required.

Network Integration

The AM-5G16-120 connects directly to airMAX basestation radios via standard N-type connectors. When paired with Ubiquiti airMAX devices and managed through the UISP platform, network engineers can monitor link performance, adjust transmit power, and optimize frequency coordination across multiple sectors. The antenna's gain characteristics are compatible with both licensed and unlicensed 5GHz deployments depending on regional regulations.

Installation Notes

Mount the antenna on a mast or tower structure with clear line-of-sight to subscriber radios. The lightweight design allows installation on standard pole and bracket hardware. Ensure proper cable management and grounding of the N-type connector. Always verify antenna orientation aligns with intended coverage sector before final tightening. The AM-5G16-120 can be deployed in weathered outdoor environments typical of wireless infrastructure installations.

Karl Wilson, Infrastructure Engineer

"The Ubiquiti AM-5G16-120 fills a practical niche in airMAX deployments where operators need cost-effective, moderate-gain sector coverage without overshooting target subscriber areas. The 16dBi specification and 120-degree pattern deliver balanced performance for typical 2–3 km point-to-multipoint links. Unlike narrower antennas that concentrate energy in tight sectors, this design trades some peak gain for coverage breadth—useful when subscriber distribution isn't uniform across your service area. The lightweight construction is an often-overlooked advantage on retrofit installations where existing tower mounts have load constraints. For most mid-market ISP and enterprise mesh projects, the AM-5G16-120 remains a solid choice."
