Applications of the Ubiquiti Networks AM-5G19-120 airMAX 5 Antenna
This sector antenna is tailored for a variety of professional and commercial wireless networking scenarios. Its primary application is for base station deployments in a point-to-multipoint (PtMP) setup. By mounting a Rocket radio directly onto the antenna, users can create a powerful airMAX base station capable of serving dozens of client nodes spread across a wide 120-degree area.
Here are some common use cases:
Wireless Internet Service Providers (WISPs) delivering broadband to rural or suburban areas
Campus-wide Wi-Fi networks across universities, schools, and hospitals
Public Wi-Fi distribution in parks, city squares, or outdoor malls
Surveillance systems requiring large-area camera connectivity
Industrial sites and oilfields needing remote connectivity over large geographic spans
Port and Connector Details
The Ubiquiti AM-5G19-120 antenna features two RP-SMA female connectors, designed to interface with the dual-chain outputs of compatible Rocket devices. These connectors are protected by the housing and are positioned to ensure a secure, weather-resistant connection once the Rocket device is mounted.
There are no Ethernet or PoE ports on the antenna itself, as it relies on the Rocket radio for data and power input. The antenna simply acts as a passive device directing and focusing the RF energy from the Rocket.
How Easy Is the Installation?
Installation is streamlined thanks to the integrated Rocket mount, which allows a Rocket M5 or Prism AC radio to snap in securely with no special tools. The included mounting hardware supports secure attachment to masts or poles of various diameters. The process can typically be completed in under 15 minutes by a single technician.
To optimize performance, it’s recommended to use the Ubiquiti alignment tool or signal monitoring from the Rocket OS to precisely aim the antenna and minimize interference from adjacent sectors.
Ideal for Expanding Your airMAX Network
If you’re building or expanding an airMAX network, the AM-5G19-120 offers high-capacity coverage with minimal signal degradation over distance. It’s especially beneficial when used in multi-sector configurations—mounting several units on the same mast to achieve full 360-degree coverage using 120-degree increments.
This makes it a favorite among WISPs who need scalable sector deployments without the complexity of additional antennas or cables.
