Originally I simply wanted to discover which DirecTV LNB module I need to buy to replace my current one which I believe to be bad. So I discovered this fact filled forum and then started seeing references to old/new dishes and HD TV. I plan to buy an HD TV soon and I now need to learn how to tell if my dish is old. The Dish is circa 2001 and the LNB was replaced once in 2006. Presently I have a single LNB / Module. So do I need a new dish and if so what type and what type of LNB is required ? I do not plan anything fancy, just watching football in HD. I would like to buy / install the equipment myself so any tips on where I can get a fair deal with good folks (online preferred) would be appreciated. thanks a bunch !
