RFD 900x Modem

RFD900x V2 Long-Range 900MHz Radio Modem

The RFD900x is the flagship of our best-selling X series—think of it as the long-distance runner of radio modems. Operating across the 902-928 MHz ISM band, this powerhouse is engineered for serious long-range data communication, whether you're piloting UAVs, building telemetry networks, or just really, really hate losing signal.

Built, tested, and inspected in Australia with NDAA compliance in the bag, the RFD900x delivers uncompromising performance over distances of 40 km+—no, that's not a typo—with flexible firmware options and industrial-grade reliability. It's also fully compatible with MAVLink, because what's a drone if it can't talk back?
