The Ubiquiti airMAX Sector 5AC21-60 antenna is an outdoor sector antenna for 5 GHz frequencies and the 802.11ac network standard. It features a 2×2 dual-linear polarization design, with reduced side and rear lobes to limit interference in co-located installations. It is designed for outdoor use and airMAX Point-to-MultiPoint networks.

The integrated Rocket mount allows tool-free installation of the Rocket BaseStation. The antenna is compatible with the RocketM5, while the Rocket5ac is required for optimal performance.
