What is the function of the radome?

• A. An electrically transparent window for transmission and reception of radar signals
• B. A decorative cover
• C. A structural element for landing gear
• D. A housing for a weather radar only, no transmission

Answer: (B)

The radome serves as an electrically transparent window that encloses the radar antenna, protecting it from weather and damage while allowing radar signals to pass with minimal attenuation. It’s made from radar‑transparent materials (like certain composites) and is shaped to maintain aerodynamics and minimize RF loss across the radar’s operating frequencies. It is not merely decorative, not a structural element for landing gear, and not just a housing for weather radar with no transmission—the key role is to keep the antenna safe yet RF‑transparent so the radar can transmit and receive properly.
