I just recorded a video with my Phantom 2 and a gopro Hero 3 White on a H3-3D gimbal and 500 mW video TX. I have the video TX module under the drone on the outside, and beside it there is the interference board. The video TX antenna was pointed towards the gopro so it was beside the gopro about 5 cm from the camera. When i came home and checked the video recording from the gopro it had grayish lines running horizontally all over the video at all times, it also had a blueish /purple line running vertical on the right side of the screen about 3 cm out from the edge. This vertical line was not present at all times, but appeared only sometimes for about 5 seconds at a time, the horizontal lines were present at all times. Any ideas to whats the cause for this and how to avoid it? Can it be that the TX antenna were to close to the gopro?
