Any satellite signal is going to be relatively weak compared to what you can produce on the ground. Inverse square law, and power limitations of a mobile transmitter. It's fairly trivial to set up a transmitter that saturates a slice of spectrum at an amount of power that is ridiculous compared to a satellite signal. There are still AM radio stations operating that go as high as 50kW. The satellite transmitters aren't going to exceed maybe a hundred Watts, at a great distance, and that falls off at 1/(distance)^2. |
