Flywoo Bipolar Dual 5.8 GHz U.FL Antenna for DJI O3 & O4 Pro, 90 mm

Flywoo Bipolar Dual 5.8 GHz U.FL Antenna for DJI O3 & O4 Pro, 90 mm

Product description

The Flywoo Bipolar Dual 5.8 GHz U.FL Antenna was specifically designed for the DJI O3 Air Unit and DJI O4 Pro Air Unit. Thanks to its true dual 5.8 GHz antenna design, it improves signal coverage, increases transmission stability, and ensures a reliable FPV connection—even in challenging flight environments. The 90-mm version stands out for its exceptionally light weight and is ideal for ultralight freestyle, racing, and cinewhoop builds.

The antenna features two U.FL (IPEX1) connectors, allowing for optimal use of both antenna inputs on the DJI O3 or O4 Pro. With an antenna gain of 2 × 2.8 dBi, linear polarization, and a low VSWR of ≤1.6, it offers efficient signal transmission with long range and good resistance to interference.

Weighing just 2.9 g, the 90-mm version is one of the lightest dual 5.8 GHz antennas in its class. The flexible RF1.13 cable simplifies installation even in compact FPV frames and allows for clean antenna routing without unnecessary added weight.
