If the height of a transmitting antenna is $h$, the range of transmission is proportional to which factor?
- A.$h$
- B.$h^2$
- C.$\sqrt{h}$
- D.$1/h$
Show correct answer & step-by-step solution
Correct answer: C — $\sqrt{h}$
Solution
The line-of-sight range of a transmitting antenna of height is given by the formula , where is the radius of the Earth. Thus, the range is directly proportional to the square root of the height.
