I believe the reflector must be grounded, otherwise it is useless.
i got very similar performance with ground off

I admit I am not competent enough to explain such behavior (I wish I was!)

Thanks, and you're very welcome. The antenna could be even better looking if I figured a way to cover the copper side with a thin even layer of epoxy to prevent copper from oxidizing. Unfortunately I screwed up so there are traces of bubbles visible. Otherwise, it is very easy to build (and I am sure any self-respecting FPV-er has dozens of unused whip antennas in his store )
