RF Solutions 868MHz Wire Antenna with UFL Connector

The RF Solutions 868MHz Wire Antenna with UFL Connector is a compact and flexible general-purpose antenna designed for seamless integration into your wireless projects. As a ready-to-operate solution, it requires no tuning, providing optimum range and reliability straight out of the package. Its robust heat-shrink overbody protects the internal components, ensuring durability in various environments. Ideal for low-power radio and Internet of Things (IoT) or Machine-to-Machine (M2M) applications, this antenna offers a reliable wireless link for sensors, remote controls, and data modules.

Featuring a vertical polarisation and an omni-directional design, the antenna radiates signal uniformly in all directions around its axis, making it perfect for applications where the device orientation may vary or where communication with multiple points is required. The 1/4 wavelength design is optimised for the 868MHz frequency band, a common ISM (Industrial, Scientific, and Medical) band used across Europe for licence-free short-range devices.

With a gain of 2dBi, it provides a effective boost to signal strength without being overly directional. The antenna terminates in a standard U.FL (sometimes called UFL) connector, a miniature coaxial RF connector commonly used to link PCBs to external antennas in compact electronic devices. Its 50-ohm input impedance ensures efficient power transfer and minimal signal reflection when connected to compatible radio transceivers.
