What is the most common type of antenna for GMDSS MF-HF?

Correct Answer: Option C — Vertical whip

Vertical whip antennas are the industry standard for GMDSS MF/HF installations because they provide the necessary omni-directional coverage. Their robust construction and ability to be mounted easily on ship superstructures make them superior to long-wire antennas, which are more susceptible to interference and physical damage at sea.
