Dishnetwork with Cox cable?
Anyone have experience having Dishnetwork for TV service, and Cox cable for internet? What I am specifically interested in, is can they both co-exist on the same coax cable? We are moving into our new home and Dishnetwork is being installed today. Cox will be here Monday. Our house is pre-wired with coax but I was looking at the feed coming into the house and there is only one coax line that comes in and it is connected to the cable that comes from the previous owners Dish already on the roof. I am wondering if Cox can be fed using the same line using a diplexer or similar device? Will the signals play nice with each other? I don't want Cox to have to run a separate cable into my house because it would not land anywhere near where I would have the router setup.

I don’t know if the diplexer will work, but it would be pretty easy for Cox to run a new line for the modem/router.

Technically speaking, it is possible as long as the frequencies used do not overlap. Will Dish or Cox support this? Absolutely not... one or the other may even refuse to install in this manner.

Also, keep in mind that the Dish switches and LNB require power in some cases - the cable modem wouldn’t like that much.

Yeah, that's totally not going to work. I'm staying with Cox after all. Thank you.

You can split a cable signal but not a satellite signal. Sorry.

The cable companies can use anything from 1 to 42MHz and 54 to 1012 MHz. Most of it is pretty much above 54 because the noise levels increase at lower frequencies.

After the microwave signal is converted by the LNBF, Dish operates between 950-1450 and 1650-2150 for the main signal. If you use wired Joey's, the Hoppers back feed that between 650 and 875.

That's how the signals play with one another. The switch for the new Dish stuff is located in the LNBF on the Dish. It can swap polarity for differences in transponder signals.

In regard to cable, digital signals sometimes need to be amplified with a unity gain amp or drop amp (drop amps aren't used much these days). Modems can be placed on these lines as well.

Anyway, like these other guys have mentioned, they can't co-exist on the same coax cable. You can designate one line in your house for the internet with an extra main line coming in. Dish can do that for you. Then, have one wired line for the Hopper and use wireless Joey's for everything else.

It can be done easily.

Which was a long way to say what I said.
