Cable Internet and TV

Can I splice the connection to my cable modem and plug in a TV also? Do I need some sort of a line filter? If so, roughly how much would it cost me? Thanks in advance.
 
I've never actually done it myself but I've heard of ppl taking digital cable and using a splitter to connect it to the internet and the cable box. I am not sure about the details and what you might need though.

yes.

no filter needed.

about $3.00 for the coax splitter.

with comcast NJ you can anyway.
 
I do pay for cable TV service too. I'm basically wanting to add another TV in a different room in the house. The line that goes to my modem (currently has nothing else on it) is the closest line to splice. I could probably splice the line that goes to the other TV, but it would require approximately another 100' of cable and lots of fishing through walls, etc. I'd rather splice the line to the modem if it's going to work.
 
as long as you don't degrade the signal by having too many splits, or use low quality splitters or cable, your TV signal and your cable modem should work find, including good crimps of ccnnectors to the cable. I have 4 tv's, cable modem, plus a TV tuner card in my PC all running off of my cable without any problems.

The internet service on cable is actually carried over a TV channel.
 
Yeah, but watch out when you have to call a technician out for something. If they're observant, they might notice that a filter wasn't installed on your line. I had to call a tech out to check my drop line, and when he went to the tap I guess he installed some kind of filter and took away the TV I had spliced. If anyone knows how to get rid of this or what I should look for, I'd appreciate it.
 
i'm an installer for comcast...lemme shed some light on things

for signal amps, you MUS make sure they're bi-directional. uni-directional amps will boost the signal to the modem or tv, but block the return and wont let your modem work at all

if you're gonna split the cable, go to home depot and get the Ideal brand 1GHz splitters, DO NOT USE CHEAP RADIOSHACK/RCA 900 or 600 MHz splitters. You'll also want to use RG6 cable if you're spitting, RG59 has a tendancy oof losing alot of signal after the split. also i've seen so many ppl try to do their own home wiring so sh*tty and they cant get it to work. SO they call us out, and we get there and its a frigging mess. So if you dont know what you're doing, dont even attempt trying, you're just gonna end up calling the cable company.

So maybe you can shed some light on my situation. I had a beautiful setup. And I certainly didn't do a craptastic job on the wiring as every TV in the house that was hooked up had a good picture. But like I said the tech came out and must have put something on my tap. I just want to know what it looks like and if it's easy to get off, because quite frankly I should be getting free TV with the amount that I spend on my connection 😛
 
probablly put a modem only trap on your tap.. only allows (atleast here, channel 112, which is the modem freq) to pass.. looks like a silver barrel, maybe 3 inches long
 
Yeah, I figured that's what it was. Good to know. He probably noticed my splitters when he insisted he had to check inside (I tried to keep him outside since I knew it was something with the drop line). Damn, looks like I'll have to do some stealth operations in the middle of the night 🙂
 
Either outside your house or on the pole or underground at their junction box, depending on where your cable runs outside your house.

Just be careful taking this thing off - They DO audit these things occasionally and it's very bad karma to get busted taking off your filter.

If I used a coax splitter on the outlet that my cable modem is on to add a TV to it would I notice any speed/connection problems with the modem?

Honest, you may. You won't know until you try it. I work for a cable company and we normally put a trap on the line so that you can't receive cable TV and internet if you only pay for internet.
 
Just a week or so ago, I noticed some new hardware on the line where it comes into my home. I figured it was to block TV signals. Crimped on with a large ferrule that spins so you can't take the connection apart.

Comcast internet and Dishnetwork for TV at my house.
