I see a lot of "loss of video" posts. However, I have video for some 400 feet and then it starts breaking up. I am using an android device. I live in the country, so I don't think that it could be interference, although, I do have 6 wireless cameras on my surveillance system, and they are all in the 2.4MHZ range. Is Lightbridge in that range? If so, I guess the cameras could be causing the interference at a distance, but not up close.
