Dual-Band AC Radio for Point-to-Point Links
The Bullet AC is a compact outdoor radio that combines a dual-band 2.4 and 5 GHz transceiver with an integrated N-Type antenna connector. It is built for installers who need a self-contained wireless bridge without separate RF cables or external antenna assemblies.
Gigabit Ethernet Port with 24V Passive PoE
The single Gigabit Ethernet port carries both data and power using 24V passive PoE on pairs 4,5+ and 7,8 return. An AC to 24V DC 0.5A PoE adapter is included, so no separate power supply or injector purchase is required for basic deployment.
Plug-and-Play airMAX Integration
The radio slides directly onto any airMAX sector or dish antenna with an N-Type interface, eliminating cable loss and mounting hardware. It operates from -40 to 70 °C at up to 95 % humidity and draws a maximum of 8 W, leaving headroom on typical outdoor PoE switches or midspans.

Questions about this item
What does the 300+ Mbps throughput figure mean once the radio is installed?
That is the peak airMAX AC throughput at 5 GHz under ideal conditions; real-world speed depends on distance, interference, and antenna alignment.
What does the Gigabit Ethernet port cap in practice?
The port caps wired traffic at 1 Gbps, so the 300+ Mbps wireless link will not be bottlenecked by the Ethernet connection.
What does the radio need to mount on a mast or pole?
It connects directly to an antenna via the N-Type connector, eliminating separate RF cables, and draws power through the included 24 V passive PoE adapter.
