Question

Is it necessary for a transmitting antenna to be at the same height as that of the receiving antenna for line-of-sight communication? A TV transmitting antenna is 71m tall. How much service area can it cover if the receiving antenna is at the ground level?​

Answer 1

Answer:

Line-of-sight communication means that there is no physical obstruction between the transmitter and the receiver. In such communication, it is not necessary for the transmitting and receiving antennas to be at the same height.

h=71 m

R=6.4× 10^6

d= √2Rh

d= √2×6.4×10^6× 71 = 5024.

Hope helps you! thank you❤
