Ubiquiti AF-5G23-S45 airFiber Antenna 5GHz 23dBi 45° Slant Parabolic Dish

The Ubiquiti AF-5G23-S45 is a high-performance 5GHz airFiber antenna engineered for long-range, point-to-point (PtP) wireless backhaul links. Designed specifically to pair with airFiber X radios like the AF-5X, this 23dBi directional antenna uses 45° slant polarization for enhanced signal integrity, noise isolation, and interference rejection. Its compact form factor, rugged build quality, and seamless radio integration make it ideal for service providers and enterprise wireless deployments that demand high-throughput and carrier-grade reliability in outdoor environments.

Product Features

Optimized for airFiber X Radios The AF-5G23-S45 integrates seamlessly with Ubiquiti airFiber X radios, eliminating compatibility issues and ensuring streamlined deployment. It includes a built-in bracket for quick, tool-free mounting of the airFiber X unit. 23dBi High-Gain Parabolic Dish The 23dBi gain, along with the parabolic reflector design, delivers a highly focused, narrow beam with superior directivity, improving signal strength and link stability over long distances. Dual-Slant 45° Polarization Engineered with dual ±45° slant polarization, the antenna enhances performance by reducing cross-polarization interference and improving co-location capability on towers and dense deployments. Low Sidelobe and High Isolation Its precision-engineered radiation pattern ensures low sidelobe levels, minimizing interference from nearby RF sources. High cross-polar isolation enhances multi-link performance in co-located setups. Compact, Wind-Resistant Design At just 378mm in diameter, this antenna is compact yet rugged. The integrated radome reduces wind load and protects internal components, making it suitable for harsh outdoor conditions. Industrial-Grade Construction Built with carrier-class materials, the AF-5G23-S45 is made to withstand high wind speeds and environmental stress while maintaining alignment and performance.
