Overview

The airFiber 4X (AF-4x) works with any 4.9GHz-capable MIMO antenna. This article lists the Ubiquiti antennas that can be used with the AF-4X and their corresponding gain. The AF-4X is a high-performance radio designed to work in the licensed 4.9GHz band, also known as the public safety band. A license is required to use these radios in the United States. US units operate from 4,940MHz to 4,990MHz, and international units (only for export) can operate from 4.7-4.99GHz.

Antenna Compatibility

Back to Top

The AF-4X works with any 4.9GHz-capable MIMO antenna. It is compatible with the Ubiquiti airFiber Dish 30dBi and 34dBi models, as well as the RocketDish 30dBi and 34dBi antennas. Unfortunately, since those antennas have been designed for the 5GHz band, the performance in the 4.9GHz range is lower. Therefore, it's important to consider this and use the following values in your calculations and in the data you enter into the airFiber 4X Wireless tab.
