A TV transmission tower has a height of 240 m. Signals broadcast from this tower will be received by LOS communication at a distance of (assume the radius of earth to be 6.4 × 106 m)
The maximum distance covered by the transmitter is given by:
Where hT is the height of the transmitting tower and R is the radius of the earth.
Substituting the given values, we have
As the value found is the maximum distance, all distances less than 55.4 km are valid. Hence, the answer is (b), (c) and (d).
