For an antenna tuner of the "Series" type, which of the following statements is false?
- AThe circuit is known as a Pi-type antenna tuner
- BThe circuit is known as a Series-type antenna tuner
- CThe output is suitable for impedances from low to high
- DThe input is suitable for impedance of ohms
Correct answer: A — The circuit is known as a Pi-type antenna tuner. From the official ISED question bank, verified word for word.
Why
A "Series" type antenna tuner uses components arranged in a single line, whereas a Pi-type tuner gets its name from looking like the Greek letter Pi with two capacitors and one inductor in a specific shape. The full explanation — and one for every question — is in Pro.
