What impedance does a 1/2-wavelength transmission line present to an RF generator when the line is shorted at the far end?
Pick an answer to check it.
Answer: B. Very low impedance
A half-wave line repeats its load impedance at the input. A short at the far end looks like a short, very low impedance, at the generator.
Tip: Half wave repeats the load.
