I know, I sound like a freak not knowing what Digital TV is but we have cable and that's all I know about. What I want to know, does digital TV need something outside of the house like and antenna or cable, or is everything inside the house? I want to watch all channels but without my neighbors knowing that I can. (they are always asking to watch TV in my house and sometimes I want quiet time). Please answer, what Can I do to be able to watch all channels without anyone seeing it from outside?!?!?!
