The Ubiquiti airMAX Bullet AC is a dual-band radio that operates on both 2.4GHz and 5GHz frequencies. With a dedicated WiFi management system, it can be utilised for short or long-distance links and offers speeds of up to 160+Mbps and 300+Mbps respectively. This versatile device features an N-type plug for easy connection to any antenna with an N-type female connector, eliminating the need for RF cables and minimising signal loss. Powered by 24V Passive PoE via a port at the base, it can be conveniently powered by a PoE switch or injector. Keep in mind that the Bullet AC is only compatible with other airMAX AC devices and cannot operate on both frequencies simultaneously.
