RFDFLEX2 900MHz Flexible PCB Antenna (1000mm)

The RFDesign 900MHz Flexible Antenna (1000mm RP-SMA) is a lightweight, low-profile antenna engineered for operation in the 902–928 MHz ISM band. Designed for UAV telemetry and long-range communication systems, it delivers reliable RF performance while maintaining minimal aerodynamic impact.

This antenna is optimized for free-space operation or installation on RF-transparent materials such as foam wings, balsa structures, thin fiberglass, and lightweight fuselages. It maintains better than -10 dB return loss when mounted in free space or on common UAV airframe materials, providing stable and consistent signal performance.

Designed for vertical polarization when mounted upright, the antenna radiates similarly to a vertically mounted dipole. This makes it ideal for placement on vertical stabilizers or upright airframe surfaces to maximize signal propagation.

Equipped with a 1000mm RG316 coaxial cable and RP-SMA connector, this extended-length version provides flexible routing options for larger airframes or installations requiring additional cable reach.
