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's antenna losing optimal orientation, reducing signal strength. When you bank, the antenna’s angle changes, causing signal dropouts. To fix this, first check that your video transmitter (VTX) antenna is firmly connected and not damaged. Next, consider using a circularly polarised antenna on both the VTX and your video receiver, as these maintain better signal during changes in orientation. Also, ensure the antenna is mounted vertically and away from carbon fibre or metal parts that can block signals. If your wing has a long wingspan, try relocating the VTX antenna closer to the fuselage or a less obstructed spot. Finally, test with a different channel or increase VTX power if legal and safe to do so, but be mindful of local regulations. By improving antenna placement and type, you can reduce video break-up during banking manoeuvres.
