The is a compact, lightweight 2.4GHz dipole antenna, optimized for high efficiency—over 70%—making it ideal for UAVs (unmanned aerial vehicles) used in FPV (First-Person View) applications. Its omnidirectional radiation pattern ensures reliable signal transmission and reception, crucial for maintaining a stable connection during flight.

This antenna is particularly small and comes with a 100mm long, 1.37mm thick low-loss coaxial cable, ending in an IPEX MHFI (U.FL) connector. The design allows the cable to extend directly from the bottom of the antenna, minimizing the space required within the device and making it suitable for tight spaces without compromising performance.

If you are building a DIY Arduino-based drone, this antenna would be a great addition. It features a standard micro linear whip design with a U.FL IPX connector, fitting easily onto any compatible U.FL port. However, be cautious with the connector as it is not built for frequent disconnections and reconnections.
