Question: Why does my FPV video break up when I bank the wing?

Answer: Video break-up during banking is usually caused by the FPV antenna losing line of sight or signal strength. When you bank your wing, the orientation of the antenna changes, potentially blocking or weakening the signal path between the aircraft and your receiver. To fix this, first check your antenna setup: use circularly polarised antennas on both the transmitter and receiver for better signal stability. Position the receiver antenna vertically and away from metal parts or electronics that cause interference. Next, ensure your transmitter antenna on the wing is mounted securely and not obstructed by the airframe or servos during manoeuvres. If your video still breaks up, try increasing your transmitter power within legal limits or flying at a higher altitude to maintain a clear signal path. Lastly, inspect all cables and connectors for damage or loose connections, as these can also cause intermittent video issues. Following these steps should improve your video link quality when banking your wing.
