I have 2 receivers , Viewsat Ultra and Ariza 700. I am using DN watching 119 and 148. Problem is that since i have connected the Ariza 700 (2nd one) i usually have Signal's problem. I did a test and removed one of the cables from the splitter and it started working fine. I believe its a wrong splitter . Can somebody tell me what is the problem. Any advice would be appreciated.
