Question:
A TV transmission tower antenna is at a height of 20 m. How much service area can it cover if the receiving antenna is
(i) at ground level,
(ii) at a height of 25 m? Calculate the percentage increase in area covered in case (ii) relative to case (i).
Solution:
(i) Range , it = 16 km
Area covered = 803.84 km2
(ii) Height from ground level = 25 m
Range = dm = 33.9 km
Area covered = 3608.52 km2
Percentage increase in area = 348.9 %
