Ubiquiti AF-5G30-S45 Airfiber Dish Antenna 30 Dbi

Product Description

The UBIQUITI AF-5G30-S45 is a 5 GHz parabolic dish antenna rated at 30 dBi gain, designed for use with the AirFiber point-to-point wireless backhaul platform. It delivers high-gain, narrowbeam performance suited to long-distance licensed and unlicensed band links. The 45-degree slant polarization indicated by the S45 designation supports cross-polarization isolation in frequency-reuse deployments. Network engineers and wireless infrastructure technicians install this antenna to extend or establish high-throughput microwave backhaul links between buildings, towers, or remote nodes.

This dish antenna is intended for outdoor fixed wireless deployments operating in the 5 GHz band. Typical use cases include point-to-point backhaul between two sites, tower-to-tower links, and campus or campus-edge connectivity where fiber is unavailable or cost-prohibitive. It is sold as a single unit and is designed to mount to a pole or mast at the antenna installation site. Proper azimuth and elevation alignment is critical to achieving rated gain.

Key Features

• 30 dBi gain for high-directivity long-distance 5 GHz links
• 5 GHz band operation compatible with AirFiber point-to-point radios
• 45-degree slant (S45) polarization for cross-polarization isolation in frequency-reuse deployments
• Parabolic dish form factor for narrow beamwidth and interference rejection
• Sold individually as a single antenna unit

Compatibility

Designed as an OEM-style antenna for use with UBIQUITI AirFiber 5 GHz point-to-point radio systems. No additional compatible model numbers were specified in the available product data.

Installation Notes

Installation is typically performed by a licensed wireless network technician or tower crew following applicable local codes and RF safety regulations. The antenna should be mounted to a rigid pole or mast rated for the anticipated wind load before the radio head is attached. Power to any associated radio unit must be removed prior to connecting or disconnecting RF components. Precise azimuth, elevation, and polarization alignment should be confirmed with a spectrum analyzer or the radio's built-in alignment tools before final hardware torque.
