Question

Long range transmission of TV-signal is done by

• A. space wave
• B. sky wave
• C. ground wave
• D. artificial satellite

Answer 1

The correct option is D artificial satellite

TV-signal ( $30MHz$ - $300MHz$) are not reflected by ionosphere. Therefore, sky-wave propagation is not possible and similarly ground and space wave is also not feasible. Hence, they are transmitted to artificial satellite from where they are transmitted back to the Earth.
