Sorry, did search on splitter and a lot of confusing threads as a lot of them had non SWM questions as well. Setup is SWM and Multi-room. Moving 2 boxes from upstairs to basement (building rooms). When house was constructed, only one coax line ran to basement. From the SWM splitter to the run to the basement can I put a splitter with the correct frequency range down there then run to the 2 boxes? Hope that was a enough info.
