Question

When the signal take-off angle increases, the height of scatter volume ________

(a) increases

(b) decreases

(c) it remains constant

(d) may increase or decrease

The question was asked during a job interview.

I'm obligated to ask this question of Space Wave Propagation topic in section Space Wave Propagation of Antennas

Answer 1

Correct choice is (a) increases

To elaborate: The signal take-off angle determines the height of the scatter volume. As the signal take-off angle increases, the height of scatter volume also increases. A low take-off produces low scatter volume.
