Why is satellite used for TV transmission to far places?

Explanation

The ionosphere is unable to reflect the signals above 40 MHz. TV signals have frequency range of 100 MHz to 200 MHz. so TV signals are not properly reflected by the ionosphere. So satellites are used for TV transmission to far places. Also communication satellite has an amplifier and transmitter which work with solar energy. The satellite amplifies the weak TV signals sent to it from the ground stations and them transmits them to the different ground stations from where they are relayed.
