Why does my FPV video cut out when I bank 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 orientation of your video antenna and signal obstruction. When you bank the wing, the antenna’s position relative to the ground station changes, often reducing signal strength. Here’s how to fix it:

1. Check your video antenna orientation. Use a circularly polarised antenna on both the transmitter and receiver, and mount the transmitter antenna vertically on the wing for consistent signal.
2. Avoid placing antennas near carbon fibre or metal parts, which block signals. Position antennas away from these materials.
3. Ensure your video transmitter power is sufficient for your flying range (typically 200–600 mW for wings).
4. Inspect your antenna and connectors for damage; a broken antenna can cause dropouts.
5. Try flying with a diversity receiver or reposition your ground station antenna for better reception.
6. Finally, keep your video gear properly grounded and check for loose wiring that may affect signal stability.

Following these steps should reduce video break-up when banking your wing.
