The Ubiquiti AF11-COMPLETE-LB is an airFiber 11 GHz low-band licensed backhaul system combining the AF-11 radio with an AF-11G35 35 dBi dish antenna. It is designed for long-range full-duplex point-to-point wireless backhaul and supports SISO operation with the included low-band duplexer, with MIMO available using a second compatible duplexer.
Backhaul Performance
The system supports up to 1.2+ Gbps maximum throughput and a specified maximum range of 300+ km under appropriate link conditions. The radio operates in the 10.7–11.7 GHz low-band range, subject to regional regulatory requirements.
RF and Duplexing
The included AF-11G35 antenna provides 35 dBi gain with 2.5° horizontal and vertical beamwidth. The radio supports SISO and MIMO operation and includes one low-band duplexer pre-installed for SISO operation. MIMO requires a second AF-11-DUP-L low-band duplexer.
Network and Power
The AF-11 provides one Gigabit Ethernet RJ45 data interface and one 10/100 Mbps management interface. Power is supplied through passive four-pair PoE or the terminal block using 38–56V DC. A 50V, 1.2A Gigabit PoE adapter is included.
Outdoor Deployment
The AF-11G35 dish is designed for tower and pole installations with 200 km/h wind survivability and 1538 N wind loading at 200 km/h. The radio operates from -40°C to 55°C, making the system suitable for demanding outdoor backhaul environments.
Key Features
- 11 GHz licensed low-band point-to-point backhaul system
- 35 dBi AF-11G35 dish antenna
- 1.2+ Gbps maximum throughput and 300+ km specified maximum range
- One low-band duplexer included for SISO operation
- 200 km/h wind survivability for the antenna
Applications
The AF11-COMPLETE-LB is suited to licensed carrier backhaul, WISP infrastructure, long-distance tower-to-tower links, enterprise backbone connectivity, and other fixed point-to-point wireless transport applications requiring licensed 11 GHz spectrum.
DC Supplies Product Note
The AF11-COMPLETE-LB is supplied as a complete radio-and-dish system, but MIMO operation requires an additional AF-11-DUP-L duplexer. Frequency selection and operation are subject to applicable licensing and regional regulations.
