The Ubiquiti airMAX AC AM-5AC21-60 sector antenna is engineered for high-performance Point-to-MultiPoint (PtMP) outdoor wireless networks in the 5 GHz band. Delivering a peak gain of 21 dBi with a 60º horizontal and vertical beamwidth, this antenna ensures focused, reliable coverage for demanding carrier-class deployments.

Featuring 2x2 MIMO dual-linear polarization and an innovative deflector design, it significantly reduces sidelobes and backlobes to improve noise isolation—ideal for co-location scenarios. The antenna supports advanced modulation schemes such as 256QAM, optimizing throughput and spectral efficiency.

Robust mechanical construction guarantees durability with wind survivability up to 200 km/h (125 mph). The antenna is supplied with universal pole mount, RocketM bracket, weatherproof RF jumpers, and a built-in Rocket mount for effortless installation of Rocket Prism 5AC BaseStation radios without tools. It is compliant with ETSI EN 302 326 DN2 and NDAA requirements.
