Similar to the torch lighting up an area of the earth

signals from the satellite are focused over a small area of the earth.

he area where the signals hit the earth is known as the 'footprint

signals and decode it to show us the TV pictures.

. The DTH footprint map of satellites show the signal strength,

The minimum size of dish for DTH in India is 50 cm or half meter diameter.

The values shown in the map above is the signal strength of the DishTV DTH

DTH dish size to receive those signals.

measure of a DTH satellite signal strength

transmits the DTH signals of India’s first and largest DTH service ‘DishTV

DishTV in the middle of India is only 50 centimetres or half a meter

India the signal strength decreases and you need a larger size dish antenna to receive the DishTV

the Dish TV signal strength over Pakistan is 44 dBW and to receive this weaker signal you need a larger dish,
