Why does FPV video break up when banking my wing?

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 camera or video transmitter losing line of sight or experiencing interference. When you bank the wing, the antenna orientation changes, which can weaken the signal between the plane and your goggles or receiver. To reduce break-up, first check your antenna placement on the plane; ensure it’s mounted away from metal parts or carbon fibre that can block signals. Use circularly polarised antennas on both the transmitter and receiver to improve signal stability during movement. Also, confirm your transmitter power is adequate—higher power can help but be mindful of local regulations. Try repositioning your receiver antenna on the ground or goggles to maintain a clear line of sight. Finally, verify all cables and connectors are secure, as loose connections can worsen signal loss during manoeuvres. Practising gentle banking initially can help identify if aggressive angles cause the issue. These steps should improve video reliability when you bank your wing.
