🔍 Key Concepts

• Antenna tuning and impedance matching between radio and antenna • How reflected power indicates antenna problems • Purpose of a Standing Wave Ratio (SWR) measurement

💭 Think About

• Which instrument directly tells you whether power is being efficiently transferred from the radio to the antenna, instead of being reflected back? • Which choice is specifically designed for measuring the match between a transmitter and its antenna system, not just continuity or frequency? • If the antenna is poorly matched, what reading or indication would this instrument show?

✅ Before You Answer

• Identify which device is made specifically to measure standing wave ratio (SWR) on a transmission line. • Eliminate tools that only check resistance/continuity or frequency, since those don’t directly show antenna match. • Make sure the correct choice is commonly used in radio installations to adjust/tune antennas for minimum reflected power.
