well tatasky's signal quality is very bad.if you brought dish tv you never face this.also its back after 2-3hour which is very irritating.buying tatasky is a huge mistake.
yes dishtv users also facing the same problem sometimes but compare hole sevice of tatasky with dish.dishtv goes to the top and tatasky to foot.anyways its coz of their low quality signal.hope soon ur stb get the bad quality signal again.
