I thought if you had a set top HD D* box like the Hughes D86, you didn't need an OTA antenna. Looking at the owners manual, I realize this isn't right. Here's my question: why would you run the cable from the antenna into the D* box? I would think you would go straight to the TV instead. The manual recommends using a splitter and sending one cable to the box and one to the TV or VCR. Is this to allow recording one thing and watching something else? Are there any other advantages to doing this way instead of going straight to the TV?
