Model: AF-4X

The airFiber AF-4X 4 GHz Carrier Backhaul Radio from Ubiquiti Networks is designed for long-range, Point-to-Point (PtP) backhaul links. It features a high TDD throughput and Hybrid Division Duplexing (HDD) technology that helps the device achieve low latency. The airFiber 4X also allows users to customize backhaul links or upgrade existing PtP links.

The airFiber AF-4X operates using the 4 GHz frequency band and features a range of 656,168' / 200,000m. Included with this device is a GPS antenna mount, an external GPS antenna, a metal strap, two cable ties, a 24V/1A airFiber PoE adapter with a mounting bracket, and a power cord.

  • Performance

Ubiquiti's INVICTUS silicon and radio architecture are designed specifically for long-distance, outdoor wireless applications. 

  • Backhaul

Deploy the 4 GHz model that meets your specific spectrum requirements, anywhere around the world. The airFiber X features multiple channel width options to suit your deployment needs.

  • Operation in Unlicensed Bands

Channel width flexibility (10/20/30/40/50 MHz) allows independent TX and RX channel frequency configurations virtually anywhere within the radio band to avoid local interference, and the channel centers are selectable in 1 MHz increments. You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements


Model:  AF-5G23-S45

Operating within the 5.1 to 5.9 GHz frequency, the AF-5G23-S45 23 dBi Antenna for airFiber AF-5X 5 GHz Carrier Backhaul Radio from Ubiquiti Networks produces a reliable point-to-point signal complete with a 23 dBi gain. In addition to the strength of the signal, users also benefit from a 90° beamwidth and a wind survivability rating of up to 125 mph. Installation has also been simplified thanks to the included pole mounting kit while the weatherproof design allows the antennas to be deployed nearly anywhere.

  • Powerful Performance 

The airFiber X antenna delivers 2x2, dual-polarity performance. Example of how the airFiber X antenna with an airFiber X radio can be deployed as endpoints in a backhaul link to deliver bandwidth from a WISP network out to a neighborhood tower. From there, an airMAX Sector antenna with a Rocket radio delivers bandwidth to the WISP’s customers.Hardware is designed to securely mount and maintain the position of the dish during harsh outdoor conditions

  • Bubble level allows for easy alignment
  • Shroud protects the cables and connectors from nature's elements
  • Housed in a compact form factor, antenna offers 23 dBi of gain
  • Low sidelobes reduce interference from other transmitters in the area
  • High isolation enhances performance for co-location in tower-mounted installations
  • Low-profile design with integrated radome reduces wind-loading
  • Powerful performance for long-range links
  • Seamless integration with airFiber radio
  • Pair an airFiber X antenna with an airFiber X radio to create the endpoint of a high-performance, Point-to-Point (PtP) bridge or network backhaul.
