Ubiquiti airFiber AF-5G23-S45 is a high-performance 5 GHz, 23 dBi directional antenna optimized for Point-to-Point (PtP) wireless links. Designed specifically for outdoor backhaul networks, this antenna enhances RF isolation and interference avoidance through its unique slant-45° polarization and 2×2 dual-linear (dual-polarity) design.

Featuring an integrated radome and a compact low-profile form factor (~378 mm diameter), the antenna withstands harsh outdoor environments with robust mechanical strength and weatherproof RF connectors. Its universal pole mount allows secure, tool-free installation suitable for towers and poles.

With a frequency range spanning 5.1 to 5.9 GHz and 23 dBi gain, the AF-5G23-S45 supports co-located deployments by minimizing sidelobe interference and providing at least 35 dB cross-polar isolation. It pairs seamlessly with Ubiquiti airFiber X radios (sold separately) for reliable long-range wireless backhaul connectivity.

Key benefits include:

• Improved interference avoidance with slant 45° dual-polarization


• Reduced wind loading due to integrated radome


• Weatherproof and rugged for outdoor use


• Universal pole mount system


• Compact size for space-constrained installations
