some channels come in some dont,from the basement I have an amp going into an 8 way splitter then it goes to the first floor where it is split 8 times and that takes care of the second floor, then the second floor comes from one of the leads from the basement and I put another amp and then I go into another 8 way splitter and that does the second floor . My problem is some of the cable boxes get everything and some are missing some hd channels and even news 12 . Whats goin on? What can I try ? Thanks for you help . P.S. some of the leads that are split dont have tv's on them should I put a smaller splitter?
