In any splitter output *except* the one that feeds the CM.

The possible problem is that the notch filter may not have extended low
frequency response, and so may not be able to pass the CM upstream
signal. For "pure" TV service, there's no need for splitters etc. to
have response below channel 2, and many, especially older ones, do not.
