I live in west orange, new jersey about 20 miles from new york city. I bought a silver sensor today. I'm getting an hdtv in about 2 weeks. I plugged it into my analog tv and tried to get a signal to see if it would work and i got hardly anything. Does this mean that I won't get hd either and that i just shouldn't even try to buy a box and the whole bit. I'll get hd through comcast everything but CBS!! which i really want. What should I do?
