My SWM 8 and SWS STR8 are mounted where my 4 Sat cables enter my basement. The PI for the SWM8 is mounted in my structured media cabinet about 20 feet away. I mounted the Broadband DECA in the media cabinet along with the requisite DECA PI. Can I use a Splitter as a Combiner to merge the DECA output with the SWM PI output that runs back to STR8? This will save me a run of RG6.
