The footprint of a satellite is the ground area that its transponders cover, and determines the satellite dish diameter required to receive each transponder's signal. There is usually a different map for each transponder (or group of transponders) as each may be aimed to cover different areas of the ground.

Footprint maps usually show either the estimated minimal satellite dish diameter required or the signal strength in each area measured in dBW. See the picture of the hypotetical Footprint right.

The footprint maps from SES Astra and Eutelsat show necessary antenna diameter/signal strength for satellites in Europe.

Satellite TV Service - Digital Satellite TV Dish (1292 words)
Drawbacks of Satellite TV A clear line of sight from a dish antenna to the southern sky is necessary to receive a direct signal from the satellite.Heavy rain,snow,trees and tall buildings could also causes to lose signal strength due to the dish antenna not being able to see the satellite.
Satellite are very expensive to launch, and the broadcast coverage may be as large as an entire hemisphere, but satellites more typically broadcast to a smaller area (footprint), such as a country or group of countries.
TV transmission satellites operate on internationally agreed-upon frequencies in two-bands the C band, 3.4 to 6.425 GHz, and the Ku band, 10.95 to 14.5 GHz.
Satellite phone (950 words)
The footprint of a satellite is the geographic region on the surface of the Earth within the range of signals of the satellite.
In cellular satellite phone communications systems and methods, multiple beams are provided, each of which can serve distinct geographical areas in the overall service region, to collectively serve an overall satellite footprint.
A satellite phone generally comprises a handheld device together with an antenna which may be connected to the telephone via a suitable connection and which may be deployed in a position on the ground or other suitable structure for directing into the sky.
