    My PDB has an LC filter and pads marked for Cam and VTX. I also have an Omnibus controller with video in and out for OSD. Should I plug the camera to OSD to LC filter or put the LC filter between camera and OSD?

    Cam->OSD->LC->VTX
    ...or...
    Cam->LC->OSD->VTX
    ?

    On the fcb would be better because of osd. Just ignore the pdb. But you could use the voltage from that for another component if you needed it.

    Which omnibus you got.

    The PDB has power pins next to each of the Cam and VTX video pins. Should I ignore the LC filter but still power the camera and VTX from the PDB?

    If you want osd, use the fcb. Not worth wiring the pdb to then wire that to the fcb for the osd. The fcb has its own LC filter specifically for the cam & Vtx. I'm running 2 omnibus boards one of em a micro.
