Overview
The Ubiquiti AF-24HD-US is an airFiber 24 GHz High-Density full-duplex point-to-point radio designed for high-capacity wireless backhaul. It supports up to 2 Gbps throughput over distances of 20+ km, with GPS clock synchronization and a dedicated 100 MHz channel architecture.
Wireless Performance
The AF-24HD operates in the 24.05–24.25 GHz band and supports 24.1 GHz and 24.2 GHz operating channels. It uses dual-slant polarization with 33 dBi transmit gain and 40 dBi receive gain, a beamwidth below 3.5°, and greater than 28 dB cross-polarity isolation.
Duplex Operation
The radio supports both full-duplex and half-duplex operation. Full-duplex operation uses separate transmit and receive frequencies and is designed for the highest throughput and lowest latency. Half-duplex operation allows the TX and RX frequencies to be configured for local interference conditions, with a programmable uplink/downlink ratio.
Key Features
- Up to 2 Gbps point-to-point throughput
- 20+ km maximum specified range
- 24.05–24.25 GHz operating frequency range
- 100 MHz channel bandwidth with GPS clock synchronization
- Dual-slant integrated antenna with 33 dBi TX and 40 dBi RX gain
Networking and Power
The AF-24HD provides one Gigabit Ethernet RJ45 data port, one 10/100 MbE RJ45 configuration port, and an RJ-12 auxiliary alignment-tone port. Power is supplied through passive four-pair PoE using 42–58 V DC. A 50 V, 1.2 A Gigabit PoE adapter is included, and maximum power consumption is 50 W.
Installation and Environmental Specifications
The radio includes a pole-mount kit and an external GPS antenna with its mounting hardware. The unit measures 593 × 768 × 370 mm without the mount and weighs 17.3 kg with the mount. Ubiquiti specifies wind survivability of 200 km/h and wind loading of 770 N at 200 km/h. Operating temperature is -40°C to 55°C.
DC Supplies Product Note
The AF-24HD-US is a US-regional version of the airFiber 24 HD platform. Ubiquiti notes that US product versions are locked to the US country code for FCC compliance. Professional installation, proper grounding, shielded outdoor Ethernet cabling, and operation within applicable local frequency and output-power requirements are required.
