🔍 Key Concepts

• Understand what a unilateral radio direction finder (RDF) is used for and how it differs from a simple loop antenna • Recall the basic antenna reception patterns: cardioid, figure-eight, and how combining loop and sense antennas changes the pattern • Know why removing the 180° ambiguity in direction finding affects the shape of the reception pattern

💭 Think About

• Ask yourself: a plain loop antenna alone has what kind of pattern, and what problem does that cause for determining a single bearing? • How does adding a sense antenna to a loop change the pattern—does it create one strong lobe in a single direction, or two equal lobes in opposite directions? • Which of the listed shapes is commonly associated with removing the 180° ambiguity in radio bearings?

✅ Before You Answer

• Be clear on the difference between a loop-only direction finder pattern and a properly adjusted unilateral RDF pattern • Match each choice with a known antenna pattern shape: cardioid vs. figure-eight vs. heart-shaped • Verify which option(s) correspond to a pattern that has one main lobe in a single direction, not two opposite identical lobes
