I don't know about satellite radio, but satellites in general tend to be very high frequencies. The reason they travel so far even though they have high frequencies, is because there is nothing blocking the signal between you and the satellite. If a signal at the same frequency and power was sent from earth, it probably would not go more than a few hundred feet. Also, most satellite signals are sent and received using a satellite dish which focuses the radio waves from one direction and blocks the signals from any other direction. Thats why you can receive a satellite signal of only a few watts crystal clear even though the signal is coming from space.
