Quel instrument est utile pour régler la longueur physique d'une antenne?
- AUn fréquencemètre
- BUn analyseur d'antenne
- CUn multimètre
- DUn capacimètre
Correct answer: B — Un analyseur d'antenne. Question tirée de la banque officielle d'ISDE.
Why
An antenna analyzer measures how well your antenna matches the radio's frequency by showing standing wave ratio, letting you trim the physical length until the signal flows freely. The full explanation — and one for every question — is in Pro.
