Generally, if it is outside the footprint, (and you are WAY outside), you wont be able to get it. The line is simply showing you can see they satellite in the sky, but that will not do you any good if the satellite is pointing the signal the other way.
I can see the South American satellites, but even with a 3 meter dish, I get no signal from them. It would be like trying to see the beam of a flashlight during the day. If you point it right at you, you can see the light, but if its pointed away, the daylight (noise in the case of a satellite) will keep you from seeing the beam.
That is how American satellites can use the same frequency to send signals to 6 or 8 different cities at the same time, since the people in one city will only see the beam pointed at them, and not be able to see the other ones.
