DJI O4 Image Transmission Relay — Stay Connected, Every Flight

If you're flying in rolling terrain, around shelter belts, or across large blocks where line of sight between your controller and drone is broken, the O4 Relay solves the problem. It acts as a mid-point repeater station between your remote controller and your Agras drone — taking the signal from each end and relaying it in both directions, so you maintain a stable connection and clear video feed even when the drone disappears behind a hill or into a gully.

Mount it elevated on a pole or tripod at a central point in your operation, pair it in seconds through your remote controller, and it works seamlessly in the background. For large NZ properties where terrain is the enemy of signal, this is a straightforward fix.
