What should be the height of transmitting antenna and the population covered if the television telecast is to cover a radius of 150 km ? The average population density around the tower is 2000 km - 2 and the value of R e = 6 . 5 × 10 6 m .

Question

What should be the height of transmitting antenna and the population covered if the television telecast is to cover a radius of 150 km ? The average population density around the tower is 2000 km - 2 and the value of R e = 6 . 5 × 10 6 m ., Height = 1731 m Population Covered = 1413 × 10 5, Height = 1241 m Population Covered = 7 × 10 5, Height = 1600 m Population Covered = 2 × 10 5, Height = 1800 m Population Covered = 1413 × 10 8

Radius covered, r = 2 R H T 150 km = 2 × 6 . 5 × 10 6 m H T 150 km × 10 3 2 = 2 × 6 . 5 × 10 6 H T H T = 1731 m Population covered = π r 2 2000 km - 2 = 3 . 14 × ( 150 ) 2 × 2000 = 1413 × 10 5
