Purpose and audience
The Ubiquiti Networks lbe-5ac-gen2 is a 5 GHz wireless bridge designed for point-to-point or point-to-multipoint links. It delivers 23 dBi antenna gain and 450+ Mbps throughput for long-distance connectivity. The integrated directional pattern improves noise immunity in busy RF environments. This unit suits ISPs and network builders extending broadband to remote sites.
Installation and common issues
A two-mount system allows adjustment on both axes and includes a built-in bubble level for fast alignment. The single 10/100/1000 Ethernet port connects directly to a router or PoE switch. Misalignment is the typical cause of low signal; use the management Wi-Fi to fine-tune aim before locking the mounts. Ensure the pole diameter matches the supplied brackets.
Interface limits
The Ethernet interface caps wired throughput at 1000 Mbps, so aggregate wireless performance above that rate cannot exit the port. Channel widths of 10, 20, 30, 40, 50, 60 and 80 MHz are available in PTP mode, while PTMP mode supports 10, 20, 30 and 40 MHz. Wider channels increase capacity but reduce range and spectral efficiency.

Questions about this item
How can I confirm the LiteBeam 5AC Gen 2 is delivering the expected 450+ Mbps link after installation?
Use the dedicated Wi-Fi management radio to connect a smartphone and check the airOS dashboard for real-time throughput, signal strength and negotiated channel width.
What accessories are included with the LiteBeam 5AC Gen 2 and what must I source separately?
The package contains the radio with integrated 23 dBi antenna, a two-axis mounting bracket with bubble level and a PoE injector; you only need to supply an Ethernet cable and a suitable pole or wall mount.
Which channel width should I select for a point-to-point link versus a point-to-multipoint deployment?
For PTP links choose from 10, 20, 30, 40, 50, 60 or 80 MHz; for PtMP deployments the options are 10, 20, 30 or 40 MHz.
