I bought a converter box and I can't get any channels. It says no signal. I can pick up local channels without the box crystal clear. I know some the the stations in my area are already broadcasting in digital. So what's wrong? I've turned the antenna, reset the box, and checked the make sure it was hooked up right. I have a great outside antenna ,so I went online and found out what type of antenna I'm supposed to use and I'm using the right kind of antenna. Can anyone tell me how to fix my problem and what's wrong. I don't understand how I can pick up channels without the box perfectly and not any channels with the box. I know that digital works different and that you ether get it or you don't. There's not any in between with static. Please help me!!!!
