As I have used some DTH operators before, I am very much satisfied with Tata Skywhich I am using now, when compared to other DTH operators. I have heard that some DTH operators are having some issues/problems in certain areas and during climate change. However, Tata sky is not having these problems that I heard of(or) personally experienced of. Also to my knowledge, Tata Sky is having the most number of HD channels compared to any other Operators.
