You’re right on that. It makes total sense that the vertical drone antennae have the least exposure to signal from the RC when it is right above you. A good call, though at 40 feet, I don’t think that was the cause of my total video signal loss - especially after so many flights at the 300 - 400 feet range directly above me, where the signal should have been exponentially less than that at closer range. If that were the case, I would expect that I would have had previous experiences with signal loss, or at least one occurrence on a similar flight where I had some warning of signal loss rather than just a total failure.
Who knows, the truth changes on a daily basis. Maybe you’re right on target. Clearly, the science and software in droning seems to always be in a bit of a state of flux. Appreciate your efforts. Thank you.
