🔍 Key Concepts

• Line-of-sight propagation of VHF radio waves • Difference between VHF and HF/long-range radio behavior • How antenna height, power, and cable condition influence signal strength

💭 Think About

• Ask yourself: Does VHF usually bend around the Earth or reflect from layers high in the atmosphere, or does it mainly travel in straight lines? • Which of these factors would change how far a clear, strong signal can go over the horizon from your vessel? • Which option is more related to long-distance ‘shortwave’/HF communication than to marine VHF?

✅ Before You Answer

• Confirm that marine VHF (around 156 MHz) is primarily line-of-sight, not a long-range skywave band. • Check which options would directly weaken or limit the signal from your set: cable damage, low power, low antenna height. • Identify the choice that is mainly associated with HF/shortwave skywave propagation, not normal VHF marine operation.
