Ubiquiti AF-3G26-S45 | Directional antenna | airFiber Dish, 3GHz, 26dBi


The airFiber X device together with the airFiber X antenna can be used as a high quality point-to-point bridge (PtP) or backhaul. AirFiber X supports diagonal polarization ± 45° to increase interference immunity and use SNR. The compact design allows airFiber X to be mounted on Ubiquiti antenna without the need for additional tools.
AirFiber X antennas are designed for seamless integration with airFiber X radio systems.
Ubiquiti AIRFIBER DISH SLANT 45 AF-3G26-S45 is a special directional antenna in the form of a dish, operating in the frequency band 3GHz and with a gain 26dBi. Innovative design improves radio signal isolation, significantly reducing interference and providing excellent amplification for high performance multi-point networks.
