Thanks for the warm welcome. This forum is very informative. The only way I can figure is that it uses less bandwidth and lower frequency that can penetrate the atmosphere better. But if that's the case why would C band need such a huge dish pointed in a specific direction also?
I'm asking about Sirrus and XM satellite radio vs. DirecTV and DishNet. I want to know why TV needs a parabolic dish whereas radio just needs to point in the general south direction. When I drive around in the car, the car can be in any direction and still get a signal even in the country...
I was wondering, how come with Satellite TV, I have to have a dish pointed directly at the satellite while with Satellite Radio, I can just have an antenna pointed anywhere in the sky? Is it because satellite radio is at a lower frequency or do they just push out more power?
