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 81m tall. How much service area can it cover if the receiving antenna is at the ground level?

Answer 1

Hello Student,

◆ Answer with explanation -

a) No. Transmitting antenna and receiving antenna mustn't be at same height for line-of-sight communication.

b) Service area that can be covered by transmitter antenna is -

A = 2πRh

A = 2 × 3.142 × 6.4×10^6 × 81

A = 3258×10^6 m^2

A = 3258 km^2

Therefore, transmitter antenna will cover a distance of 3258 km^2.

Thanks dear...
