🔍 Key Concepts

• Unilateral radio direction finder (RDF) basic operation with a loop antenna • What a loop antenna can and cannot tell you by itself (ambiguity of direction) • Purpose of adding a sense (vertical) antenna to a loop system

💭 Think About

• Think about the limitation of a loop antenna pattern by itself: what ambiguity exists when you try to take a bearing? • Ask yourself: does a sense antenna measure direction on its own, or does it modify/improve the loop antenna pattern? If so, how? • Consider what "unilateral" implies about the bearing information produced by the combined antenna system.

✅ Before You Answer

• Verify what kind of direction ambiguity a plain loop antenna has (two possible directions 180° apart). • Check how combining the loop + vertical sense antenna changes the reception pattern (from a figure-8 to something else). • Confirm whether the sense antenna’s function is to take bearings alone or to resolve the 180° ambiguity of the loop.
