Built for WISP backhaul

The Ubiquiti Networks AF-5XHD-US is a 5 GHz point-to-point radio designed for wireless internet service providers who need licensed-band performance in unlicensed spectrum. It delivers 1+ Gbps throughput over distances up to 100 km using proprietary TDMA technology and a dedicated spectral analysis radio. The unit operates as a PtP master or slave and includes integrated GPS synchronisation for ±0.2 ppm frequency accuracy across sector deployments.

Passive PoE with wide voltage range

Power is supplied through a 24 V 1 A gigabit PoE adapter using either 2-pair or 4-pair passive PoE on the two GbE RJ45 ports, accepting 18–54 V DC input. Maximum power consumption is 24 W with a typical draw of 18 W, and the radio is rated for continuous operation from –40 °C to 55 °C without active cooling. AES-256 encryption and 2+ Mpps packet processing add minimal latency to the data path.

Compact IP67-ready form factor

The radio measures 224 x 82 x 48 mm and weighs 0.4 kg, mounting directly to compatible Ubiquiti airFiber X or RocketDish antennas for a complete outdoor link. An included IP67 upgrade kit seals the Ethernet and GPS connections against dust and water ingress. Dual GbE ports allow a wired backhaul or management path without extra switching hardware, and selectable channel bandwidths from 10 MHz to 100 MHz let the installer match spectrum availability.

Questions about this item

How do I mount the AF-5XHD and align it, and what step do installers often miss?

Mount the radio on a compatible Ubiquiti 5 GHz antenna using the included bracket, then aim precisely using the built‑in alignment tone; the step often missed is enabling GPS sync before final torque so frequency accuracy reaches ±0.2 ppm instead of ±2.5 ppm.

What component will need replacement first on a long‑term PtP link?

The passive PoE injector (24 V, 1 A) is the only field‑replaceable part; the radio itself has no moving components or user‑serviceable modules, so plan to swap the injector if power delivery degrades after years of outdoor exposure.

At what sustained throughput does the link hit its first hard limit?

The radio’s processing ceiling is 2+ Mpps; at maximum 100 MHz channel width this translates to the advertised 1+ Gbps throughput, so sustained traffic above that packet rate will queue or drop before any thermal or power limit is reached.
