🔍 Key Concepts

• Radio direction finder (RDF) principles on ships • How atmospheric conditions can change radio wave paths (e.g., night effect) • How metallic structures near the antenna can affect bearings

💭 Think About

• Think about what could cause the apparent direction of an incoming radio signal to be different from the true direction, even if the equipment itself is correctly calibrated. • Consider whether radio waves always travel in straight lines, or if the ionosphere and time of day can alter their path. • Ask yourself if moving or adding metal objects near the loop or antenna system would change the electromagnetic field around it and therefore influence the indicated bearing.

✅ Before You Answer

• Verify whether bending or reflection of radio waves can change the indicated bearing without changing the instrument’s internal calibration. • Check if nearby metal objects or structural changes can create errors in the direction-finding antenna system after installation. • Confirm whether these factors would affect the accuracy of the bearings, even if the equipment was originally calibrated correctly.
