I have a Direct TV single feed coming into my house to a receiver. But I have two authorized, working DirecTV receivers of which I pay. I want to split the feed into a splitter or switch to control both these boxes separately to two separate TV's from one DirecTV feed. I was told this is possible. So my question is, what switch or splitter must I buy? I tried a regular 3 to 1 splitter and it didn't work. So I think I have to get a special Satellite switch of some sort? Can I buy it Radio Shack? If I can, can someone specifically tell me what it is or better yet link me to it. Please let me know. Thank you.
