Why does my FPV video signal break up when banking my wing?

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

Answer: When banking your wing, the FPV video signal can break up due to the orientation of the video transmitter’s antenna relative to the receiver. Most antennas are directional, so tilting or rolling the aircraft changes the angle and reduces signal strength. To improve this, first check that both your transmitter and receiver have matched antenna types (e.g., circular polarised) and ensure antennas are properly mounted, ideally with some vertical clearance from metal parts. Next, try using diversity receivers or antennas with wider reception patterns. Also, verify your transmitter power is appropriate and that the antenna cables are intact with no damage. Finally, consider repositioning the antenna on your wing to maintain a better line of sight during manoeuvres. Practically, before flying, perform a range test with your wing banked at different angles to spot weak spots. These steps will help reduce video break-up during banking and improve overall FPV signal reliability.
