2.4 GHz BaseStation Sector Antenna with 15 dBi Gain and 120-Degree Coverage for airMAX Networks
The Ubiquiti airMAX AM-2G15-120 is a 2x2 MIMO sector antenna built for 2.4 GHz point-to-multipoint base stations. With 15 dBi of gain across a 120-degree beamwidth, it covers a full third of the horizon from a single sector while maintaining enough gain to reach distant CPE devices. The antenna operates across the 2.3 to 2.7 GHz range and mounts directly to any Rocket M series radio using the included bracket and weatherproof RF jumpers.
The AM-2G15-120 is the 2.4 GHz, 120-degree model in the airMAX sector antenna family. Ubiquiti offers sector antennas across 2.4 GHz and 5 GHz bands in 60-degree, 90-degree, and 120-degree beamwidths, so network planners can mix sector widths to match subscriber density and tower geometry. Three AM-2G15-120 antennas on a single tower provide full 360-degree 2.4 GHz coverage.
Where the AM-2G15-120 Fits
- WISP base stations serving residential subscribers where 2.4 GHz penetration through foliage and building materials matters more than raw throughput, and a 120-degree sector covers a wide service area from each tower face
- Rural broadband deployments where a Rocket M2 radio paired with this antenna reaches distant CPE devices with 15 dBi of gain, and the 2.3 to 2.7 GHz operating range accommodates both standard and extended frequency plans
- Multi-sector tower builds where three 120-degree antennas provide complete 360-degree coverage from a single pole, each sector handling its own subscriber load independently
What the AM-2G15-120 Delivers
- 15 dBi gain, 120-degree beamwidth: Covers a full third of the horizon with enough gain to maintain links to distant subscriber devices. Three sectors on one tower provide seamless 360-degree coverage.
- 2x2 MIMO dual polarization: Two independent RF paths on vertical and horizontal polarizations double spatial streams and improve throughput in multipath environments compared to single-polarization antennas.
- 2.3 to 2.7 GHz operating range: Covers the full 2.4 GHz ISM band plus extended frequencies used in licensed and semi-licensed deployments. One antenna handles standard 2.4 GHz and extended band plans.
- Rocket M bracket and pole mount included: Ships with a universal pole mount, RocketM mounting bracket, and weatherproof RF jumpers. The antenna mounts to the radio and pole in a single assembly with no extra hardware to source.
- Built for tower deployment: Rugged construction at 8.82 lb handles sustained wind loading on tower installations. The 27.6-inch form factor fits standard sector antenna spacing on multi-sector poles.
What Is the Range of a Sector Antenna?
Range depends on the antenna's gain, the radio's output power, and the CPE antenna on the subscriber side. The AM-2G15-120 provides 15 dBi of gain at 2.4 GHz, which paired with a Rocket M2 radio typically reaches CPE devices at distances of 5 to 15+ kilometers depending on terrain, foliage, and subscriber antenna quality. The 120-degree beamwidth trades maximum range for broader coverage compared to narrower 60-degree sectors, making it the right choice when subscriber density is spread across a wide area rather than concentrated in a narrow corridor.
