Here is my dilemma. I currently have dish network with american and some international channels that are not offered by time warner cable. I want to switch the american channels to time warner cable but want to keep the international channels from Dish.

Is it possible to have both dish and time warner signal travel through same cable? or do i need to lay another cable from outside of the house?

I currently have one RG6 cable carrying both Dish and Comcast cable by using two splitters. They must be good quality and the type that is direct through one in/out and one isolated in/out. There is usually a small picture on this type which shows what looks like a capacitor in the line. This connection is used for the cable.
The Dish path must be able to supply a voltage change from the receiver to select the proper bands coming from the dish/LNBFs or switches.

I'm not recommending this setup, two cables are better, but in my case it works for the bedroom TV. MY family room setup is with two cables, actually three cables as I also have two Dish receivers, along with the cable box.

The one in the family room does not have a cable box but the TV is capable of tuning the local HiFef signals via its QUAM tuner. Works great but confuses the heck out of my wife.

I was out to the Doc for an MRI yesterday at 6PM and when I came home I found that she had successfully turned on the TV and Dish receiver in the family room and had sound coming out of the Onkyo sound system. Surprised the heck out of me but then I saw that she had the Harmony 880 by her side. Wonderful, wonderful.

You can't use "splitters" to combine cable and sat, but you can use diplexers, which look like 2-to-1 cable splitters.

However, if you have any 2-room receivers, you are probably already feeding diplexed signals down your sat lines to feed the 2nd TVs, in which case you need additional, separate cables run for the cable signal.

not quite true, you can use a regular splitter/combiner to combine the signals on the vhf/uhf side of a diplexor as long as tv2 is modulated to channel that is not being used by the cable signal. I'll diagram it and post it here in a little bit.

Why would you want the cable guy to mess with your sat cable, make them run new cable to the TVs

Wouldnt this involve making holes in the wall? I dont want to make any more holes in the walls.

 

[Nick]

I have both -- separate cables.

 

[oljim]

More holes or more problems.

 

[BaldEagle]

Did this in my motorhome using two diplexers.

In most areas, especially now with digital and analog, cable is using all of the 5-800 MHz spectrum on the cable, leaving no free channels for the modulated TV2 signal.

I suppose there are smaller cable systems out there that don't, but I expect those are the exception, not the rule.

you could use something like this then. Unless I'm completely misunderstanding what its for.... :grin:

well, that one is for HAM radio, but it or something like it would work i think

I knew the correct term was diplexer but darn, just couldn't remember the name. Old age muddles the brain some times.
Anyway, I believe my description of it was correct so if he followed that he would get the correct item...diplexers.

You could use a coax switch, yes, but you'd have to place it near the source (remember: the goal is to NOT run another cable to the TV), so you'd have to get up and walk to the other room, or to the service entrance, to change the switch. I doubt anyone will find that an acceptable solution, even though it would technically work. (I don't know of any remote-controllable coax switches that would be suitable).

This would not work, it is for 1.8-30 MHZ, 50 ohm, and it does not have the right connectors.

This is all new to me so I apologize in advance if this is a stupid question...are we talking about having cable feed through the dish dvr so we could potentially see cable in the channel line-up (and possibly record their programming) or is this just another input to the tv?

Thanks.

 

[oljim]

No reason to feed cable to the DVR, it will do nothing with cable, will not show in EPG and can not record. Just feed cable to RF in on TV

Cable and Dish would be going into different inputs into tv.

The reason I chose that one is that the switch was outdoor, but the controller would be indoor. Not saying that one in particular would work, but something along the same design lines...

I said "or something like it." I figured it probably wouldn't work. But if could find one for the right frequency with the controller seperate from the switch like that, i think it would work really well for his situation. Now, I don't know if such a beast exists, but at least I'm giving potential ideas.
