You connect to the FPV camera ground. You have to split it to the iOSD mini and your vTx. It is a common ground.

The grounds can cause ground loops, the PMU is grounded, so pretty sure there not required.
I haven't got mine connected and i have clear video, heard of guys having them, getting bad interference and then removing them and the problem went away...

I have a TBS Disco Pro, LC s from "IVC Store - FPV Gear" - didn't put it in, in the end - power from the TBS core is pretty clean.

My Boscam T353 is 12v, so draw this from the TBS core vTx power pads.

Wiki -LC Filter it will tell you all you need to know and more in effect is a voltage filter to remove any unwanted electrical noise to keep video etc, signal clean.

TBS = Team Black Sheep produce a nice machines called Discovery & Discovery Pro....
