RFDFLEX1-ux Flex Antenna (30cm u.Fl)

The RFDesign 900MHz Flexible Antenna (300mm u.FL) is an ultra-lightweight, low-profile antenna engineered for operation within the 902–928 MHz ISM band. Designed for UAV telemetry and long-range data link systems, it provides reliable RF performance with minimal weight and installation footprint.

Optimized for free-space operation or mounting on RF-transparent materials such as foam wings, balsa structures, thin fiberglass, and lightweight fuselages, the antenna maintains better than -10 dB return loss even when installed on EPP foam. Its design makes it relatively insensitive to installation conditions, ensuring consistent performance across different airframes.

The antenna incorporates integrated feed point matching and a built-in balun for feed cable isolation, helping improve signal integrity and reduce unwanted interference. Black solder resist with gold-plated pads supports clean electrical connections.

Equipped with a 300mm cable and u.FL connector, this antenna is well-suited for compact telemetry radios and UAV systems requiring lightweight, space-efficient RF solutions.
