For an antenna tuner of the "Series" type, which of the following statements is false?
B
Answer
Interference, EMC, and safety
Type
A
The circuit is known as a Series-type antenna tuner
B
The circuit is known as a Pi-type antenna tuner
C
The input is suitable for impedance of 50 ohms
D
The output is suitable for impedances from low to high
Answer Notes
A series-type antenna tuner places its reactive components in series with the load to cancel out the antenna's reactance and achieve an impedance match. Like most commercial tuners, it is designed to take a 50-ohm input from the transmitter and match it to a wide variety of output impedances.
The statement that is false is identifying it as a "Pi-type" antenna tuner. A Pi-network requires shunt (parallel) components bridging to ground on both sides of a series component, which is fundamentally different from a simple series matching circuit.
