🔍 Key Concepts

• GMDSS MF-HF antennas used on most SOLAS vessels • Difference between vertical whip antennas and long wire antennas • How polarization (vertical vs horizontal) affects marine sky-wave and ground-wave communications

💭 Think About

• Think about what type of antenna is physically practical to mount on most ships for MF-HF use • Consider which antenna type can operate effectively over a wide frequency range (2–30 MHz) used by GMDSS MF-HF equipment • Look at each option and ask: Is this something you actually see on commercial ships’ masts for MF-HF radio?

✅ Before You Answer

• Verify which antenna type is commonly installed on SOLAS cargo and passenger ships for MF-HF GMDSS • Check which options describe realistic shipboard antennas versus equipment mainly used for satellite systems • Confirm that the chosen option’s polarization and physical form match typical MF-HF marine installations
