We have had broadband internet in our home office for about 5 years
and a TV just for the children to play video game, recently as they
are older they have decided they want to watch cable TV in there, my
question is can I use a splitter and have my modem and TV running from
the same wall outlet, if so do I have to use specific cables?

Any help is appreciated.

Chris.

Maybe.

It depends on your signal strength and SNR currently. You may get
away with a regular splitter. If it doesn't work or causes an
increase in packet loss, a directional coupler (DC) is better. DC's
have a low-loss output, and a higher loss output while a traditional
splitter loses 3dB on both outputs. See also:

To minimize headache, use quality cable and professional terminations
with as short runs as possible. RG-6 is what's recommended. RG-11
would be overkill. RG-59 is to be avoided. And be careful with
connector selection if you choose to make your own. See also:

Good luck!

Thank you for your help, just a few questions if you have time, how do
I find my signal strength and where would I get a DC from?
I'm about to check out the links you gave me, if any of my Qs are
answered there feel free to ignore me.

Yours,
Chris.

Any decent modem will have a web page you can access that has that info.
I think Motorola is at: http://192.168.100.1/signal.html, not sure if
passwd access restricted. My Terayon: http://192.168.100.1/diagnostics_page.html
Passwd: icu4at! Than to: http://192.168.100.1/modemRfPage for numbers

You should be able to get a coupler online or at a local electronics store.
google: CATV cable directional coupler

Todd & Bill's posts are spot on. I'll just supplement with Scientific
Atlanta's WebSTAR line (DPC/EPC2100), sometimes rebadged "Comcast":
