Bell Canada’s ExpressVu service (now called Bell TV) uses the small, gray digital satellite dishes that are now a familiar sight around North America and Europe. These dishes receive signals beamed down directly from a group of satellites in orbit around the Earth; ExpressVu dishes use a satellite in geosynchronous orbit around the equator, which means that all dishes in Canada point roughly south. To receive signals, the dish must be pointed at exactly the right spot in the sky. The orientation of the dish will depend on where it is being set up.
