Question
Which of the following must be connected to an antenna analyzer when it is being used for SWR measurements?
Answer Options
- A) Receiver
- B) Transmitter
- C) Antenna and feed line
- D) All these choices are correct
Correct Answer: C
Explanation
An antenna analyzer is a testing instrument that contains its own low-power signal source, directional coupler, and receiver. It is specifically designed to measure the electrical characteristics of an antenna system.
When measuring SWR (Standing Wave Ratio), the analyzer must be connected directly to the system being measured, which is the antenna and feed line. The analyzer sends a signal down the feed line, and measures the forward and reflected waves that result from the antenna’s impedance, calculating the SWR.
