I have digital cable tv in my house which the cable company provides the cable box. The tvs with the cable box has digital cable while the other tvs that don't have the cable box can watch the analog cable channels of course. Here is how my wiring is setup, I'll try to describe it as best I can. The main cable comes into the house and is connected to a 2 way splitter. From the splitter one cable goes to the living room upstairs (~25 feet). The other one goes to the back of the house (~80 feet) which is then connected to a 3 way splitter. From the 3 way splitter another cable (~25 feet) goes the the rooms upstairs and finally a 2 way splitter so both tvs upstairs. The tv in the living room has no reception problem since it is closest to the source. The tvs in toward the back of the house that have analog cable has a bit of snowing images on some channels. And the tv with digital on some channels either cannot receive or appears skipping. The cable splitters say 5-900mhz on them. I am using the RG-6 quad shield cables, my old wiring was RG-59 which I replaced because the wiring was very old. With the new RG-6 wiring it improved the reception a bit. The questions I have are if the 2.4ghz splitters are better than the 900mhz splitters, I though you only needed the 2.4ghz if you have satellite tv. And my other question is if an amplifier would improve the reception. Thank you.
