View Full Version : Coax (cable tv) over cat5e?

My current living conditions make it literally hell to run another cable to where I want to place a tv at.

Although I have already went through hell and back bringing an Ethernet cable to this room.
More specifically its a cat5e direct burial cable that was pretty expensive.

Is there anyway I can run a coax cable through some of my unused pairs in my ethernet cable, just as you could run a phone line along side of internet?

If not what is a good name in wireless coax transmitters or are they even worth my time?

Get yourself a hub/switch/router and then you can run off that as many as you like.

..... Let me illustrate what I am trying to do.

As you can see the unused wires won't even be conected to either my pc or router, but rather to the coax.
I wan't to know If I can send a coax singnal through the unused pairs in my cat5 cable and how I can connect them or convert them.

Personally I would stay away from the wireless transmitters. Might be me but I've never been happy with any of them. One idea is to use a product like this one (http://www.svideo.com/500039.html) but it's not HD in case you have a HDTV.

Another idea is to use something called a balun they have many different types like this cheap one here (http://www.buy.com/prod/pair-of-passive-cctv-security-camera-cat5-video-baluns-connection/q/listingid/52759344/loc/111/212323442.html).

Those would work, but I am trying to still utilize the cable for internet, but at the same time transmit coax cable tv through it.
Actually I can't see that picture well, but is it only requiring 2 pairs to be plugged in?

In addition It keeps referencing security cameras and scanners... How would this work for tv?

It's still a video/audio signal passing through the cable. I don't think that two Ethernet wires would transmit video/audio properly bud. I could be wrong though. Most of the audio AND video ones I'm seeing look to have some minor circutry involved so.

I think Tessco would know more about the actual line voltages/ohms and stuff but you could try it on the cheap by using this type of balun here (http://www.summitsource.com/product_info.php?ref=1&products_id=6494)

Get two of these and connect the two wires to each side and see what happens.

Have you contacted Comcast? If you haven't, I would see if they can figure out a solution.

I came across a powerline converter system (here (http://www.brickhousesecurity.com/secureview-video-transmitter-receiver-system.html)), but it appears to only do video (and I know nothing about this company, btw). I can't recommend any wireless systems as the ones I have seen tend to be pretty cheesy.

I am definitely interested in seeing your ultimate solution for this.

Good luck!

Yea I don't see how I can lose trying with those, their like 30 cents lol.

wow thats a diagram for you, I don't think you should use coax for Internet use, or cat5 for TV ,they are made specifically to be tuned for there own purposes, there ohms are totally different, If you used coax, for internet you would suffer with all kinds of crosstalk throughput interferences just to name a few.
Back in the old days coax was used as in thicknet/thinnet but again they were tuned.
Maybe you could find some kind of filter rod to sort the interference out like a ferrite rod but hey i don't know,mad idea you got going there.

lol, I'm avoiding running a coax cable at all costs lol.
Also I'm intending to use cat5 for coax, not coax for cat5. :wacko:

Is their anyway I could stream cable tv over my network, if near my router I had a coax cable and still be able to switch channels from another computer?

*side note* bought two really trashy baluns as I am just interested in testing their performance with cable tv over a cat5 line....
Megabyteme I'll let you know how it works, and how I eventually get it set up.

the balun what Detale said use is the best bet then,you would have a balun coming out of your pc video/sound, plug a cat 5 into it,then plug the other balun into your tv with the other end of the cat 5.
As far as remotely changing channels on another pc,use logmein/vnc/cygwin with openssh remote desktop,just to name a few, and then just log onto your pc and do you stuff.
We will get you there in the end :)

Using a balun I will be able to switch channels with a remote to the tv/monitor.

I was talking about running it over a network.

Logmein/openssh remote desktop to the pc you can control everything via the network like you are on your pc.

Wait, to be clear. Are you trying to watch cable TV over this line or stream movies from your PC?

Watch cable tv, I already have my server with movies on it that I could stream from any local machine.

Is this just standard cable or are you planning to use digital?

Those baluns that Detale posted might work. But I'm betting that it wouldn't work all that well, and probably best with the low channels (1-13). I doubt it will work at all with digital cable or with a cable modem though.
There are actual RF to CAT5 baluns but they are very expensive. $60 each (and you need two, and I have no idea how well they work).

Also CAT5 is not shielded. The reason we use coax is because it is shielded. The CAT5 will probably pick up a lot of interference (especially if it's running in the same cable as your network/internet). It may even interfere with your network connection...


Keep in mine that everything I've said is just guesses. I really have no idea if this will work and for 30 cents a balun it's obviously worth a shot.
If it was me I'd just run the coax.

I ran 100 feet of coax cable around the house consuming a little over 2 days of my time.

Problem solved, now I just have to figure out how to turn off a monitor that has no remote.

*by the way I'm still going to test the baluns when ever they get delivered.

If your laying in bed at 1 in the morning you won't want to get up to turn off the monitor lol.

Actually, there should be some other remote controlled power-plug devices that you can find.

buy an extension cord, an electrical box, a switch, and a plate, and make your own redneck remote. :lol:

lol redneck remote, I was thinking of just running an extention cord you can pull out of the wall by the bed.:lol:

or just tie a string to the cord that reaches to your bed. Bit more luxurious, no ugly cords running across your floor.:lol:
