A TV transmission tower antenna is at the height of 20 m. How much service area can it cover if the receiving antenna is (i) at ground level, (ii) at the height of 25 m? Calculate the percentage increase in area covered in case (ii) relative to the case (i).

Answers (1)

As given in the question,

For the first part

i) Range of the signals, it = 16 km

Area covered by the waves = 803.84 km2

ii) Height of antenna from ground level = 25 m

Range of the antenna = dm = 33.9 km

Area covered in transmission = 3608.52 km

Thus, the percentage increase in area covered in case (ii) relative to the case (i) = 348.9 %
