I am a total newbie so sorry if my questions sound trivial or stupid. I live in Charleston, sc on the Atlantic coast. I have an elevated house with a 180 degrees view on the ocean. Can I receive signal from Intelsat 903 at 34.5W? In general, how do I know what satellites I can get depending on my lat/long?
What size of dish do you recommend? The bigger, the more satellites I can get?

Thanks
