What about satelite dishes?

They broadcast tv signals using satelites so if you live in france you can watch a TV program from Japan

''Satellite Dish - Azimuth, Altitude and Skew

Each satellite is put into the sky at specific coordinates, similar to a longitude and latitude for navigating on land. These coordinates, the azimuth, the altitude and the skew, tell your dish exactly where to look. The azimuth is the East/West location while the altitude or elevation tells you how far North of the horizon (ground level) you need to go. The skew is a calculation to compensate for the natural curvature of the Earth itself. With these three coordinates, you can accurately point your satellite dish to receive transmission from the right satellite.''
