Directional antenna Ubiquiti AF11-Complete-LB

The Ubiquiti AF11-Complete-LB is a directional antenna operating in the 11 GHz licensed band, designed as part of the airFiber 11 radio system. With a high 35 dBi gain and a compact, efficient form factor, this antenna supports gigabit-class wireless links for carrier backhaul, building-to-building enterprise connections, and public safety networks. It is intended for wall or pole mounting and connects using 10/100/1000Base-T(X) cabling. Power is supplied via DC or PoE within a 38–56 V input range, and the unit comes in a white housing suited to various installations.

Advantages

The directional antenna provides high gain (35 dBi) for long-range, low-latency links while avoiding congested 5 GHz spectrum by operating at 11 GHz. Its compact design is optimized for the airFiber 11 system and supports standard gigabit Ethernet cabling (10/100/1000Base-T(X)). Flexible mounting options (wall or pole) and dual power options (DC or PoE, 38–56 V) simplify deployment in carrier, enterprise, and public safety scenarios.

Suitable for

• Carrier backhaul links
• Building-to-building enterprise connectivity
• Public safety and emergency communications
• Long-range point-to-point wireless links

How to use

Mount the antenna on a stable wall or pole with a clear line of sight to the remote endpoint. Connect the AF11-Complete-LB to your airFiber 11 radio or compatible radio equipment using a 10/100/1000Base-T(X) Ethernet cable. Supply power through DC or a PoE injector within the 38–56 V range. Align the antenna precisely toward the peer unit to maximize signal strength and verify link quality in the radio management interface.

Recommendations

Place the antenna to maintain unobstructed line of sight and sufficient clearance from nearby structures or vegetation. Use appropriate grounding and lightning protection for outdoor installations and follow local licensing rules for the 11 GHz band.
