I have an old c band dish and im thinking about getting rid of it and getting one of the dish packages offered with a fta receiver. Can I retrofit my C band dish with an fta lnb? If not, can you suggest what type of dish is better for southeastern US (Covington, LA) I am particularly interested in a satellite that is W 45 degrees which carries unscrambled programming of all the PR (Puerto Rico) local channels. Thanks in advance! bigec2002
