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

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

Answer: Video breakup during banking is usually caused by the FPV transmitter's antenna orientation and signal obstruction. When you bank the wing, the antenna may no longer be pointing optimally towards your receiver, weakening the signal. To fix this, first check your antenna placement on the model—ideally, position it vertically and away from carbon fibre or metal parts that can block the signal. Next, try using a circularly polarised antenna on both the transmitter and receiver to improve signal stability during manoeuvres. Also, ensure your transmitter power is adequate (e.g., 200–600 mW) for your flying distance. Finally, test with different bank angles and note if the problem worsens when the antenna aligns poorly. Adjusting your flying style or adding diversity receivers can help maintain video quality during aggressive turns. Keeping antennas clear and oriented correctly is key to consistent FPV video.
