A TV transmission antenna is tall. How much service area it can cover if the receiving antenna is at the ground level?
(radius of the Earth )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Range of Signal in Space Wave Propagation is given by, Range=2hR. Therefore, service area =πrange2=π2hR2=π×2×6400×10340=512π×106 m2
