Q

Which of the following represents the best standing wave ratio (SWR)?

🔍 Key Concepts

• Standing Wave Ratio (SWR) measures how efficiently power is transferred from the radio to the antenna • A perfect impedance match between transmitter, feedline, and antenna gives the ideal SWR • Higher SWR values mean more power is being reflected back toward the transmitter instead of being radiated

💭 Think About

• Which SWR value indicates the closest condition to a perfect match between the radio and antenna? • As SWR numbers increase (for example, from 1:1 to 1:4), what happens to the amount of power reflected vs. power radiated? • On many marine radios, what SWR range is generally considered safe and efficient for normal operation?

✅ Before You Answer

• Identify which option has the lowest ratio (closest to equal forward and reflected power) • Recall that the ideal SWR is the one that indicates no reflected power • Eliminate any choices where the second number is much larger, indicating a poor match and high reflection
