Product Information
Full details
The DJI O4 Air Unit Pro Antenna is an essential component for FPV drone pilots using the O4 transmission system who require consistent, high-fidelity video feeds. It serves as a reliable replacement for your Air Unit Pro, ensuring that your long-range signal remains robust and uninterrupted during high-speed maneuvers. While it is engineered for extreme performance, users should note that as a sensitive signal-receiving component, it requires careful installation to avoid cable damage or signal interference.

FAQs
Are these antennas compatible with older DJI FPV systems?
No, these are specifically designed for the DJI O4 transmission protocol and are not backwards compatible with O3 or earlier systems.
Can I replace just one of the two antennas?
While it is physically possible, it is highly recommended to replace both to maintain balanced signal diversity and optimal performance.
What is the maximum range supported by this antenna?
The system supports up to 15km of transmission range, provided the environment is clear of significant interference and the drone is within line-of-sight.
How do I secure the antenna to the frame?
Use high-quality antenna tubes or 3D-printed TPU mounts to keep the antennas in a vertical orientation while protecting them from propeller strikes.
What should I do if the U.FL connector breaks?
The U.FL connector is fragile; if broken, the entire antenna assembly must be replaced to prevent video failure.
Troubleshooting
Video signal is intermittent or drops frequently
Check the U.FL connection on the Air Unit to ensure it is fully seated and verify the antennas are not blocked by carbon fiber or batteries.
Reduced range during flight
Inspect the antenna cables for kinks or exposed shielding and ensure the antennas are oriented away from the drone body.
Pros and Cons
Pros
- Genuine DJI replacement part ensures hardware compatibility
- Maintains high-quality video feed for O4 systems
- Supports up to 15km transmission range
- Essential for stable FPV flight performance
Cons
- Installation requires precision to avoid damaging the U.FL connector
- Specific to the O4 Air Unit Pro and not compatible with older systems
- Exposed antennas are susceptible to damage in high-speed crashes
Setup, Compatibility & Care
Installation of the antenna involves connecting the delicate U.FL connector to the Air Unit Pro main board. Always ensure the connector 'clicks' firmly into place. Avoid bending the antenna cables at sharp angles, as this can cause internal shielding damage. Compatibility is limited strictly to the DJI O4 Air Unit Pro system. For care, keep the antenna tips free from mud and debris after flights, and inspect the U.FL connection periodically for any signs of loosening due to frame vibration.
