What impedance does a 1/8-wavelength transmission line present to an RF generator when the line is shorted at the far end?
Pick an answer to check it.
Answer: C. An inductive reactance
A shorted line shorter than a quarter wave looks inductive at the input. At 1/8 wave, it is an inductive reactance.
Tip: Short and short line = inductor.
