I currently have Directv. When my contract runs out, I want to buy a Glorystar system and replace D* with Glorystar. I know I have to replace the dish but can I use the existing D* coax cabling running from the dish to the house or do I have to replace that? The coax is relatively new, about 3 years old. Also, I want to get basic locals only cable for my local channels. Can that cable be plugged into the back of the Glorystar receiver so that I can change local channels from the receiver? If not, how do I handle that? Thanks in advance.
