Which of the following can be measured with an antenna analyzer?
Velocity factor
Cable length
Resonant frequency of a tuned circuit
All these choices are correct✓الإجابة الصحيحة
الشرح
All three follow from the analyzer's ability to measure impedance against frequency. A tuned circuit shows its resonance directly, and a length of line left open or shorted resonates at frequencies that reveal its electrical length, from which physical length or velocity factor is calculated.
