The Ubiquiti AF-5G30-S45-US is a 5 GHz, 30 dBi Slant 45 antenna designed for long-range point-to-point wireless links using Ubiquiti airFiber X radios. Its 650 mm reflector provides focused RF performance, while the dual-linear polarization and 30 dB front-to-back ratio support directional backhaul deployments.
RF Performance
The antenna operates from 5.1 to 5.9 GHz and provides 30 dBi of gain with a maximum VSWR of 1.6:1. Its dual-linear polarization and Slant 45 configuration are designed for airFiber X wireless backhaul applications.
Point-to-Point Deployment
The AF-5G30-S45-US is an antenna component rather than a complete wireless radio. It is designed to pair with a compatible 5 GHz airFiber radio to create a directional point-to-point link.
Outdoor Construction
The antenna is designed for outdoor tower and pole installations, with 200 km/h wind survivability and a specified wind loading of 790 N at 200 km/h. The included mounting hardware provides a universal pole mount and airFiber radio mounting interface.
Key Features
- 30 dBi gain at 5 GHz
- 5.1–5.9 GHz operating frequency
- Slant 45 dual-linear polarization
- 30 dB front-to-back ratio
- 200 km/h wind survivability
Applications
The AF-5G30-S45-US is suited to carrier backhaul, WISP infrastructure, tower-to-tower connectivity, and long-distance fixed wireless point-to-point links where a high-gain directional antenna is required.
DC Supplies Product Note
The antenna is supplied as a directional antenna assembly with its mounting hardware and weatherproof RF jumpers. A compatible 5 GHz airFiber radio is required separately to form a complete wireless link.
