Dish and cable on the same wire?

[slimoli]

Can I use a diplexer and run a single cable carrying both DishNetwork and my local cable signal? I need to keep Dish since my wife wants a foreign channel not available on cable but I am dying to switch from 'E" to cable.

Many Thanks,

Sergio

Yes. there must be NO other device (switch, power inserter, nothing) between the 2 diplexers.

Thanks Simon. I know that there are several types of diplexers and currently I'm using the cheap one (40-2150). My plan is to get rid of my roof antenna and use one of the diplexer input for the satellite cable (from the switch) and the other input for the local CATV. Do you see any reason why I should upgrade my diplexers or the cheap one is OK?

Thanks again.

No idea what you mean by "cheap one".

I won't tell you what we pay for ours, but they don't cost much. In fact, I'll sell you all you want for $3 each, minimum 2, shipping included.

It's a good idea to use a matched pair (same make & model).

Not sure what you mean by "40-2150". If referring to frequencies, what you need is: OTA port: 0-900MHz, Satellite port: 950-2150MHz. OTA can have a lower high limit, a higher low limit (up to 40MHz) and the satellite side can be wider (lower low, higher high).

That number looks like a radio shack cat number.

Thanks again. Searching the internet I found diplexers from 3 to 17 bucks in the same store. The US$17.00 looks bigger but also has 2 IN and 1 OUT . My question was if I need the fancy one or any diplexer can combine/separate CATV/satellite. I will need 8 pieces and will go for the 3 bucks.

Any of them should work. I'll PM you my shop number.

You should avoid diplexing the line if it also carries cable internet service. If it's only for TV then that's ok.

It depends what frequency the cble internet is being sent on. I have never had an issue diplexing cable internet and satellite in Washington. I have heard that it will NEVER work in Texas though...???
