Antenna Ubiquiti AF-5G23-S45

The Ubiquiti AF-5G23-S45 is a 5 GHz, 23 dBi high-gain antenna engineered for long-range wireless links and compatibility with AF-5X radios. Sized at 378 mm x 290 mm x 378 mm and finished in white, this directional antenna uses 45° slant polarity to integrate seamlessly with airFiber X installations and improve link stability and coverage.

Advantages

The antenna’s 23 dBi gain concentrates RF energy for extended range and stronger received signal levels. Its 45° slant polarization matches AF-5X radio polarization to reduce polarization loss and simplify alignment. With a compact form factor and a 3.4 kg weight, the unit is manageable for tower or mast mounting and designed for outdoor wireless backhaul scenarios.

Suitable for

• Point-to-point long-range wireless links
• Backhaul connections with AF-5X airFiber radios
• Rural or wide-area coverage where high gain is required

How to use

Mount the AF-5G23-S45 on a stable mast or tower using appropriate clamps and ensure the antenna is aimed precisely at the remote endpoint. Connect the antenna to an AF-5X radio following the radio manufacturer’s RF connection instructions and maintain the 45° slant polarization alignment between paired antennas. After mechanical installation, perform fine alignment while monitoring signal strength and link quality on the AF-5X radio.

Recommendations

For best results, use the antenna with AF-5X airFiber radios and maintain clear line of sight between endpoints. Verify polarization orientation (45° slant) on both ends and perform regular inspections of mounting hardware and RF connections to preserve link performance.
