What information can be obtained with an antenna analyzer?
- A Gain of the antenna
- B Front-to-back ratio of the antenna
- C SWR of the antenna system over a range of frequencies
- D Radiation pattern of the antenna
Correct answer: C — SWR of the antenna system over a range of frequencies. From the official ISED question bank, verified word for word.
Why
An antenna analyzer measures how well your radio matches the antenna by checking the standing wave ratio, or SWR, across many frequencies at once. The full explanation — and one for every question — is in Pro.
