it's not that hard to jam open satelite channels. Just put a big air-baloon over each city(or even much larger areas), positioned aroung the direction the satelite is, and you can easily send a similar, but more powerful signal than the satellite and jam the reception. Why iran doesn't do this is an interesting question.
