5 GHz BaseStation Sector Antenna with 19 dBi Gain and 120-Degree Coverage for airMAX Networks
The Ubiquiti airMAX AM-5G19-120 is a 2x2 MIMO sector antenna designed for 5 GHz point-to-multipoint base stations. With 19 dBi of gain across a 120-degree beamwidth, it delivers higher throughput capacity than its 2.4 GHz counterparts while covering a full third of the horizon from a single sector. The antenna operates across the 5.15 to 5.85 GHz range and mounts directly to any Rocket M5 or Rocket 5ac series radio using the included bracket and weatherproof RF jumpers.
The AM-5G19-120 is the 5 GHz, 19 dBi, 120-degree model in the airMAX sector antenna family. The higher gain compared to the 2.4 GHz AM-2G15-120 compensates for the increased path loss at 5 GHz, maintaining competitive link distances while taking advantage of the wider channel widths and cleaner spectrum available in the 5 GHz band. Three AM-5G19-120 antennas on a single tower provide full 360-degree 5 GHz coverage.
Where the AM-5G19-120 Fits
- WISP base stations prioritizing throughput where 5 GHz spectrum provides wider channels and less interference than 2.4 GHz, and a 120-degree sector covers a broad subscriber area from each tower face
- High-density suburban deployments where the 5 GHz band's additional spectrum and wider channel options support more simultaneous subscribers per sector than 2.4 GHz base stations
- Multi-sector tower builds where three 120-degree antennas provide complete 360-degree coverage from a single pole, each sector delivering independent 5 GHz capacity to its subscriber base
What the AM-5G19-120 Delivers
- 19 dBi gain, 120-degree beamwidth: Higher gain than the 2.4 GHz AM-2G15-120 compensates for 5 GHz path loss while maintaining broad 120-degree coverage. Three sectors provide full 360-degree service from one tower.
- 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.
- 5.15 to 5.85 GHz operating range: Covers the full 5 GHz UNII spectrum including UNII-1, UNII-2, UNII-2e, and UNII-3 bands. One antenna handles all standard 5 GHz frequency 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 13 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 Maximum Range of a 5 GHz Sector Antenna?
Maximum range depends on antenna gain, radio output power, channel width, and the CPE antenna on the subscriber side. The AM-5G19-120 provides 19 dBi of gain at 5 GHz, which paired with a Rocket M5 or Rocket 5ac radio typically reaches CPE devices at distances of 5 to 20+ kilometers in clear line-of-sight conditions. The 5 GHz band achieves higher throughput than 2.4 GHz at similar distances but is more sensitive to foliage and obstructions, so clear or near-clear line of sight between the sector and subscriber antennas is important for maximizing range.
