For an antenna tuner of the "L" type, which of the following statements is false?

An L-network (L-type) antenna tuner consists of two reactive components—one in series and one in parallel—arranged in the shape of the letter L. When configured to step up impedance, it effectively matches a standard 50-ohm transmitter to high-impedance antennas, such as end-fed wires. The false statement is that this circuit is suitable for matching to a vertical ground plane antenna. A standard quarter-wave vertical ground plane antenna naturally exhibits a low impedance (typically around 36 ohms), meaning it does not require a tuner configured for high-impedance matching.
