I guess here is where I admit that I am technologically inept Everyone I know bought the HD converter box and an antenna to go with it. They are all getting lots of new channels...... I hooked up the box and the new antenna, turned on the TV and got ....... No improvements at all. As a matter of fact, I actually got MORE channels with out the HD stuff hooked up. Now, I will admit that the pictures are grainy and sometimes just in black and white. But, the pictures that I do get with the HD improvements are really not much better. Can anyone out there give me some pointers ??
