For VHF signal broadcasting, ___________ km2 of maximum service area will be covered by an antenna tower of height 30 m, if the receiving antenna is placed at ground. Let radius of the earth be 6400 km. (Round off to the Nearest Integer) (Take π as 3.14)

Step-by-Step Verified Solution

d=2hR

area = πd2

Area = π(2hR) = 3.14 × 2 × 30 × 6400 × 103 . m2

= 1205.76 km2

≈ 1206 km2
