🔍 Key Concepts

• VHF antenna gain vs. beamwidth (how a higher gain changes the shape of the radiation pattern) • Difference between horizontal and vertical radiation patterns on a rolling/pitching boat • How small craft motion in waves affects a narrow beam antenna

💭 Think About

• How does increasing antenna gain usually affect the width of the main lobe of the radiation pattern? Does it get wider or narrower? • On a small boat in rough seas, what happens to a very narrow vertical beam when the boat pitches and rolls? Where might the strongest part of the signal be pointing? • Which answer choices describe a problem that would specifically show up more on a small, moving vessel compared to a large, stable one?

✅ Before You Answer

• Check how high-gain marine VHF antennas (e.g., 6 dB, 9 dB) are described in study materials in terms of beam being flatter/narrower vs. broader. • Verify which options refer to beam shape (pattern) versus an operational effect (like losing signal as the boat moves in waves). • Make sure the disadvantage you pick is something that would be more serious on small craft in rough weather than on a large, steady vessel.
