I'm probably not alone, but I still see neither reliable information nor consensus on the anti-interference board. There are those that insist is related to jello (which I'm disinclined to believe) and those that appear to say it's to clean up FPV, and imply it's only for the DJI fpv gear. I don't use theirs but an Immersion RC 600mW vtx instead. Do I need the board? Any real information available?
