🔍 Key Concepts

• Propagation characteristics of different radio bands (LF, HF, VHF, UHF) • How ionospheric reflection/skip supports long‑distance communication • Which bands are typically used for line-of-sight vs beyond line-of-sight communications

💭 Think About

• For very long distances over the horizon, which frequency ranges can ‘bend’ or reflect off the ionosphere instead of just going straight? • Among the listed bands, which ones are normally used for ship‑to‑ship or ship‑to‑shore local communications, and which are used for long‑range circuits? • Continuous operation for long-haul links usually avoids bands that are heavily dependent on terrain and line-of-sight. Which options fit that description?

✅ Before You Answer

• Recall that VHF (Very High Frequency) and UHF (Ultra High Frequency) are primarily line-of-sight and commonly used for short‑range marine communications and radar. • Think about which band is historically associated with shortwave and long-distance maritime communications. • Verify which band descriptions in your study materials are linked to over-the-horizon, long-distance, continuous operation rather than local communications.
