VTX and goggles on the same frequency but I get snow/static

[LordDount]

Help! VTX and goggles on the same frequency but I get snow/static, after plugging & unplugging the battery it sometimes will connect, all lights in VTX are working and talking to FC, and all wiring&connections are good including antennas, thanks for the help

It could be noise you are using 4 in one ESC?

yes, I don't think it's noise it's completely static but after plugging and unplugging the battery a dozen times it connects and the video is perfect.

You can use one thick Plastic sheet (You can build your own one, It is cheap), just paste cover two side with heat\thermal insulation tape, then place it in between FC and ESC.

FC to closed to ESC, and ESC's MOFSET noise will do much way to affect FC.

Then It would be fined. I'm also do it this to help to reduce much noise by solder grounding a extra wires from VTX GND to Camera GND by the way.
