What two ways could a dip meter be used in an amateur station?
- A To measure resonant frequencies of antenna traps and to measure a tuned circuit resonant frequency
- B To measure antenna resonance and impedance
- C To measure antenna resonance and percentage modulation
- D To measure resonant frequency of antenna traps and percentage modulation
Correct answer: A — To measure resonant frequencies of antenna traps and to measure a tuned circuit resonant frequency. From the official ISED question bank, verified word for word.
Why
A dip meter works by detecting when a circuit absorbs energy, which happens at resonance, making it perfect for finding the exact frequency where antenna traps or any tuned circuit naturally oscillate. The full explanation — and one for every question — is in Pro.
