:thumbsup:It sounds like you need to make sure the splitter has what's called D.C Pass-through.
No idea what you are talking about. It sounds like you want to use the splitter as a power inserter to put 12vdc along with the dish signal on the cable going up to the attic? Is the 8 way amplified maybe??Just a quick question. I have a high quality [2ghz] 1 to 2 splitter. Can I use the 2 out ports for my dtv antenna cable and my 12vdc amp and run the in port to my 8 way splitter up in the attic? I used the same setup for my 2 dtv antennas and it worked fine.
