A dipole antenna will emit a vertically polarized wave if it is:
- A very high above ground
- B mounted vertically
- C mounted horizontally
- D too near to the ground
Correct answer: B — mounted vertically. From the official ISED question bank, verified word for word.
Why
A dipole antenna radiates a wave that matches the direction of the antenna itself, so when the antenna is mounted vertically, the electric field points up and down, creating a vertically polarized wave. The full explanation — and one for every question — is in Pro.
