OK, I have 4 rooms right now that I have cable drops in for TV. Kitchen, 2 bedrooms and the living room. I have the 3rd bedroom as well as the basement rec. room to put drops in as well.
I can easily do this with a splitter and lots of 75 ohm coax. The problem is signal strength. HDTV signals usually have higher performance requirements. My issue is that right now, standard cable will have a signal drop if the line is split too much. Depending on the number of splits made, the splitter can push the presented range on the signal out of the acceptable performance range of coax. Add to that the requirements of HDTV for signal quality and the splitters can wreak havoc on your signal.
So, the answer is an amplified splitter. You can get one for about $50 from most places. They are quite simple consisting of signal amplifiers for each or a bank of coax outputs. Of course if you are using the signal from broadband, you put the splitter after the modem connection so it doesn't interfere with the data signal even though it shouldn't.
So what I want to know is there anyone here using an amplified splitter for their cable TV signal and if so, are you using it with an HD signal? If you are using it with an HD signal, do you notice any performance problems?
