Sorry if I added extraneous and potentially confusing material...
For *most* relatively simple system applications of splitters you shouldn't
common mode problems. So don't worry about it.
But if, after installing your splitter, you encounter *unexplained*
overloading problems, etc... then you might have to learn to deal with it.
The solutions to common mode problems often seem subtle and obscure to the
uninitiated. With a little understanding, which requires a knowledge base
analog techniques, methods of mitigating undesired common mode effects can
be learned. The causes of these longitudinal signal problems never appear
on schematic drawings, and or system diagrams, they are all in the nature
of "stray" or "parasitic" effects which are not obvious to the casual
If you encounter them, it helps a lot if you have a mentor...
If you are not sure you are having common mode problems and are just
"splitters" then paying a little more for an "inductive/transformer" type of
better than just using a resistor matching pad splitter.
