splitting cable to a LOT of tvs Can't Post
hey, im getting ordinary analog cable and i want to split it, which isnt a difficult task for me normally, but this time i'll be splitting it to 4-13 tvs, and im worried about the signal being crap. i was hoping some people here could offer me some suggestions on what kind of equipment would be best to maintain a decent signal. what i know so far:

-as for the splitter, 5-1000 MHz frequency range should do it. The splitter should provide EMI isolation.

thats it. are there any particular specifications on the splitter/cables i use? are amplifiers necessary? is there a way i can test the signal strength (aside from watching TV of course), like say with a device that reads the signal and gives an output rating?

also, there is no internet going through this signal, just analog TV. no need to worry about that, at least for now.

thanks for reading

The fcc requires that every cable operator in the usa provide 0db of signal or more on every channel to every TV in the home as this is the optimal signal for the best TV performance. once you start getting below 0db lets say a -5db you start getting noise and snow in the signal. If you re amplify a bad signal you get a stronger bad signal so you will want to re- amplify at around +5db to 0db and I would recommend a 10db amp, you don't want to much signal.

So here is what I would do. Lets say you have +5 db on your lowest channel and you want 14 outlets. a 2 way splitter has 3.5db of loss a 4 way splitter is 3 2way inside so you have 7db of loss and so on. if you take a 2 way splitter and feed 2, 8 way splitters you will have 14.5db of loss with a +5db in to a 10db gain amp into your splitters you will have a +.5 db to each set. One other thing to consider is the loss of the cable from the splitters to the TV set. On rg6 cable ch. 2 looses 1.6 db per 100 ft and ch. 70 looses 4.6 per 100ft
