ok i have a stupid question

[radotvguy]

I been seeing and hearing about this change from analog to digital in feb 2009. Here is my question , which convertor box is the better one to buy . Second question is , i have a roof antenna which i installed less then two years ago and the paperwork said it was digital compatible?? Does this mean i just hook up my coaxial from the antenna to this convertor box which in turn converts the signal back to analog , then will i be able to still use the rotary tuner on the tv or are the channels changed by a button on the box . I am looking to get a box this weekend to prepare myself . I have not really looked into this switch till recently so i am somewhat ignorant to what i have to do . Can anyone chime in .
