Please help. All 3 Comcast boxes work with no issues, Tivo has poor signal in the room I want to use it in, averaging 73% and SNR of 29 on the working channels. Poor channels averaging 67% with SNR of 26. When I take TIVO downstairs it works great with over 90% signal strength. So here's the wiring setup. Cable comes into basement and goes into a 3-way splitter. I have the the 2 with the 7 db loss going to the basement TV and main floor TV. These TV's are fine and if I hook Tivo up down there, it works fine too. A 3rd cable that leads upstairs is on the 3.5 db loss port. Once it gets upstairs there is another 2 way splitter. One goes to bedroom with Comcast box and works fine. The other goes to the TIVO. So here's the deal, a lot of the research I've done before making this post talks about hooking up amp where the cable comes into the house. I don't see much talk about an amp to just 1 TV. I'd really like to just AMP the TV that I need, Signal strength is great on 2 downstairs TV's as it is. What do I want to buy to increase signal strength to just 1 TV? I want to buy a quality product. Adjustable if possible, don't want to have a problem of too much signal. Thanks in advance for your help.
