Q

What is indicated by the bearing obtained from the use of a bilateral radio direction finder?

🔍 Key Concepts

• Radio direction finder (RDF) basic principle: it gives you a bearing of the signal source relative to the direction-finding station • Meaning of bilateral in direction finding: the antenna pattern and ambiguity between two possible directions • Difference between a single, unique bearing and a bearing that could apply along two opposite directions on the same line

💭 Think About

• When a direction finder measures a bearing to a radio transmitter, what geometric feature on the chart does that represent: a point, a line, or something else? • If the equipment is bilateral, does it clearly distinguish which end of the line the signal is on, or could the reading be ambiguous between two opposite directions? • Which choice best describes how a bilateral RDF bearing is plotted on a chart: through the ship, through two stations, or as a line that could be valid in two opposite directions?

✅ Before You Answer

• Be clear on what bearing means in RDF: is it toward one known position or along a line of possible positions? • Think about whether bilateral implies a unique direction or a two‑direction ambiguity along the same line. • Eliminate any choice that describes more than one bearing (e.g., two stations) instead of a single measured bearing from an RDF.
