Technician exam question T7C02
Subelement T7, PRACTICAL CIRCUITS· Group T7C
Which of the following is used to determine if an antenna is resonant at the desired operating frequency?
- A.A VTVM
- B.An antenna analyzer (correct answer)
- C.A Q meter
- D.A frequency counter
WhyAn antenna analyzer is used to determine if an antenna is resonant at the desired operating frequency. An antenna analyzer measures an antenna system's impedance and SWR across a range of frequencies, showing directly whether it's resonant at the frequency you intend to operate on, answer B. A VTVM (A) measures voltage, a Q meter (C) measures a component's quality factor, and a frequency counter (D) measures frequency, none of which characterizes an antenna's resonance the way an antenna analyzer does.
