I don't have a dish, and I am not really "educated" fully in FTA, but from what I understand you can get FTA on your big dish. There are 2 bands, C band and Ku. What you have is C band, and what the company was refering to was converting your dish to Ku, I believe. I think C band may offer more unscrambled content. You may need a new LNBF, I think you may need a new reciever if the one you have is really old.
