AM-3G18-120
The AM-3G18-120 from Ubiquiti is a carrier-class 3 GHz sector antenna engineered for high-performance Point-to-MultiPoint (PtMP) deployments. Designed to integrate seamlessly with Rocket M BaseStations, this antenna enables operators to build scalable, high-capacity base stations in licensed and lightly licensed 3 GHz bands.
Featuring 2×2 MIMO, 18 dBi gain, and airMAX TDMA technology, the AM-3G18-120 delivers reliable throughput, excellent noise immunity, and predictable latency—ideal for WISPs, ISPs, and enterprise outdoor networks. The antenna’s wide 120° sector coverage, strong cross-polarization isolation, and electrical downtilt help optimize coverage while minimizing interference.
Built for outdoor use, the AM-3G18-120 includes pole mount hardware, RocketM mounting bracket, and weatherproof RF jumpers, making deployment fast and straightforward.
