Using a splitter for Cable TV/Cable Internet?

[clicknext]

I only have one cable line in my room. Can I use a splitter between a TV and a cable modem?

 

[kalster]

yes

yep thats how I had it when I was on Cable

 

[Antisocial Virge]

yeap

Get one with the highest impedance possible.

Yes.

As long as you use decent quality splitters, it is no problem. My signal is split twice(one HQ grounded, one cheapish radio shack) before it gets to my cable modem, and I have no loss in dB.

Even with the best splitters I thought you lose 1/4 - 3/4 the signal. At least that's what Comcast said when they came out to our house and found a two and three way splitter.

Impedence is measured in ohms, right? I don't see any product sites that have that information. They only say mhz. I'm looking at a Radioshack one that's 5-2300mhz. Is that good enough?

 

[Megatomic]

you are correct clicknext. my splitter doens't specify the impedance but it does show the freq. range and the SNR. The 5-2300MHz splitter you found, does it list the SNR? That one's got a better range than mine, I might want to check it out.

It's this one here. Does not list SNR. Would that be signal-noise-ratio?

 

[Megatomic]

Yep. I think that DSV 50 might be hinting at a 50dB SNR but I can't be certain... My splitter has only a 35dB SNR but it's definitely sufficient for my needs. It splits my cable modem line giving me an input to my Leadtek TV card.

Not only should you get a high quality splitter, you should also get good cables. If you still have issues, check for other splitters throughout the house. In my case, the tech installed a bad splitter.

<--- recently got Comcast, and went through all this. (I have a tv-tuner card hooked up, along with cable internet.)

sorry, that's just not possible... to lose no signal when the signal is split.
even the BEST quality splitters lose signal, even a fraction of a dB.
