Comparing a parabolic reflector with a flat plate antenna of the same size: A. The flat plate antenna has a considerably smaller beam width. B. The parabolic reflector has a considerably smaller beam width. C. The parabolic reflector generates less side lobes than the flat plate antenna. D. The flat plate antenna generates less side lobes than the parabolic reflector.
Understand the Problem
The question includes a series of multiple-choice inquiries related to radio wave propagation, VDF (VHF Directional Finding), and related phenomena. It involves understanding various principles of physics and radio communication to arrive at the correct answers.
Answer
B
The final answer is B
Answer for screen readers
The final answer is B
More Information
Parabolic reflectors typically produce narrower beamwidths compared to flat plate antennas, leading to higher directivity and gain.
Tips
A common mistake is confusing beamwidth with side lobes. Beamwidth relates to the direct focus of the beam, whereas side lobes refer to unwanted radiation directions.
