How EXACTLY does the dual-tuner "Separator" made by DishNetwork work?

Be careful, now. It is NOT a TV splitter. It enables both tuners of a dual-tuner receiver to use only one cable from the Dish Pro Plus LNBF. Choose your answers carefully...I am a communications engineer.|||This is an interesting article.

There are many ways to multiplex two analog signals. They coul d use simple RF modulation with two different carrier frequencies.|||Well, the dish has to have at least 2 LNB's on the dish, both get combined at 2 difference frequencies and passed through 1 cable. Next it needs to be separated with some type of dishnet splitter. Then from there, 1 cable goes to Sat 1 IN, and the other to Sat 2 In.





Iam not sure what you are asking, but if your talking about how 1 dish set top box can operate 2 different tvs at the same time with different remotes then hopefully the answer above is correct.|||Interesting question.





Sounds like a simple band pass filter


separating UHF from VHF.

P.S. If this is wrong, I'll know Tuesday or Wednesday... 'cause I'll ask one of the engineers at echostar.|||If you're a communications engineer, then you already know the answer. It really is just a splitter. They tried to tell me that a splitter is a passive device, but their Separator is an active device. Unfortunately, it has no power plug, uses no batteries, and the signal from the LNB is incapable of powering it.





And besides, you're sending one signal to two tuners, just like a splitter does for two TV's.
