About Satellite Footprint Maps
If you are a consumer looking to get a satellite dish property, or even a communications network or provider setting up a system, then satellite footprint maps will be of much interest to you. A satellite footprint map determines the geological area of coverage for a system, as well as the actual diameter of a satellite dish, which is necessary to figure out what is needed to receive a digital transponder signal. A satellite footprint measures the coverage of a transponder's ground area. There actually are a number of maps, one for each transponder. Satellite footprint maps will provide a measurement of area signal strength or an estimate of the required minimal dish diameter for the given area.
When defining the coverage area on a satellite footprint map, it is key to know that coverage maps generally indicate areas of service and reception for radio stations which transmit signals. Such maps can be useful not only for radio purposes, but for cell phone tower coverage, and for television stations. It is for satellite purposes that the maps are referred to as "footprints." When equipment is functioning properly, coverage maps can tell you the area in which people should be receiving good reception of the satellite signal. Also, you can determine alternative transponders where you can get stronger reception, or at least usable production out of the service.
Among the limitations for these maps is the fact that there can be parts of the footprint that are poorer in reception quality. No one should take the boundary lines on the coverage area to mean that the coverage is limited to that area, because satellite footprint maps merely present a general coverage area, particularly in the case of large regions. For example, just because a particular map ends roughly at the border of Colorado does not mean you might get sparse coverage in Wyoming. Despite the fact that broadcasters and carriers make it a goal to avoid dead zones and islands in their networks, it is very difficult to accomplish and therefore you will likely see cracks in coverage at some points within a coverage network.

There are big advantages to having knowledge of satellite footprint maps. In some cases, it may be possible to be location where a signal spills over to your location. Be sure that you remember that it is always wise to check the legality of anything before you attempt it for yourself.
