I just learned about FTA and have no clue about it whatsoever. I was looking at the list of Indian channels which are FTA and they are available on many different satellites. If I can get FTA hindi channels here in California, what do I need, which channels can I get, if I want to watch channels that are on different satellites do I need a dish for each satellite? Can someone please give me a detailed information on this topic or point me to a source where I can find the info?
