## Summary description

The Ubiquiti airFiber5 is a high-performance sector antenna with a gain of 23 dBi, designed for the 5 GHz frequency band. It supports various modulation schemes including 1024-QAM, 256-QAM, and QPSK, ensuring efficient data transmission. This white antenna is wall-mounted and operates on a power requirement of 42-58VDC. It complies with RoHS and has CE, FCC, and IC certifications, making it a reliable choice for outdoor wireless networking.

## Long description

The Ubiquiti airFiber5 is a purpose-built outdoor sector antenna and backhaul radio for long-range, point-to-point and carrier-class network links in the 5 GHz band. With a 23 dBi gain and support for high-order modulations such as 1024-QAM, 256-QAM and QPSK, it delivers high throughput and is intended for installations that require robust, low-latency wireless backhaul performance.
Advantages
The airFiber5 combines a high-isolation dual-antenna design with optimized RF engineering to perform reliably in noisy outdoor environments. It provides real-world throughput up to 1.2+ Gbps and supports full-duplex FDD operation for sub-millisecond latency, making it suitable for carrier-class backhauls. The product is designed for outdoor mounting, has RoHS compliance and CE/FCC/IC certifications, and is available in a weather-resistant white enclosure.
Suitable for
Long-range point-to-point links (up to 100+ km under appropriate conditions)
Carrier-class network backhaul with low-latency requirements
High-throughput wireless bridges between sites
Outdoor installations requiring sector antenna coverage in the 5 GHz band
When it may not be suitable
This device operates in the unlicensed 5 GHz band and its deployment must follow local regulations; it may not be appropriate in regions where that spectrum is restricted or requires licensing. For short-range indoor Wi‑Fi coverage or consumer-grade home networks, the airFiber5 is over-specified and a dedicated indoor access point would be more appropriate.
Key specifications
Frequency band: 5 GHz (unlicensed, subject to local regulations)
Gain: 23 dBi
Supported modulations: 1024-QAM, 256-QAM, QPSK
Throughput: up to 1.2+ Gbps (real-world)
Duplex mode: FDD full-duplex for \<1 ms latency
Mounting: outdoor wall or pole mount
Power: operates with 42–58 V DC input

Weight: 16 kg
How to use
Mount the airFiber5 outdoors on a suitably rated mast or wall bracket with a clear line of sight to the remote endpoint. Configure radio parameters, modulation and channel settings via the compatible management interface, ensure correct alignment for maximum link quality, and provide the required DC power through the recommended PoE injector or power supply within the specified voltage range. Verify local regulatory compliance for 5 GHz operation before final deployment.
What to consider before purchase
Local regulations and allowed 5 GHz channels in your country
Required line-of-sight and site clearances for long-range links
Power infrastructure capable of supplying 42–58 V DC
Structural support for outdoor mounting and wind loading
Usage recommendations
For best results use precise mechanical alignment tools and spectrum analysis during installation, select the highest modulation supported by link conditions, and monitor link performance to adjust settings for optimal throughput and latency.
