Yup it is called a diplexer. Looks like a splitter but is actually a high freq dc pass low freq dc block device. You use them in pairs. Many here don't like them but I find they work great. I have used a lot of them. You will pay a lot for them at Rat shack so be careful. If you can't find a reasonable place to buy them let me know I have quite a few of them.testguy said:Can i combine dish and cable signel in one cable using some device like splitter. Please help.
