Go back to the Glossary indexFootprintSatellites broadcast their signals directionally. Each company tries to focus the beam of their broadcast as narrowly as possible to match the areas in which they expect to serve customers; this is important because of the need to conserve power on a satellite.The area the beam reaches is called the satellite's footprint. It does not have uniform intensity - think of it like a flashlight beam where it is strongest near the center and fades away from that. Footprint maps look like topographical contour maps, with lines indicating the strength reaching that point, listed in dBW.
