75 ohm terminator needed for Power Inserter?

I have read that it is recommended that on a SWiM setup, the power inserter should be installed on a dedicated line. Right now, the "Signal to IRD" on my power inserter goes to a H24 in my office.

If I move this cable to one of the outputs on my 8 way, do I need to cap the IRD output on the power inserted with a 75 ohm terminator?
