I tried to resolve my problem with setting up Prodelin dish to recieve Nasa and Norad satellite locations about a year ago. I finally just bought from Galaxy Marketing a ESX741 LNB and conical scaler for this offset dish. Is there any unsual circumstances I need to know about getting my LNb aligned for this particular dish. As you can see I am using this commercial dish and mount that used to recieve KU signals but want to get AMC-18/12c. Just for starters how do I know if what I am using is pointing correctly at the dish itself. Also is there a way to know where I am pointing on the dish surface. I was thinking about using a laser center on mount, should the horn be pointing directly to center or just below center. Anyway I need some help. Thanks Stan Gamble
