Advanced Qualification · A-007 Feedlines and matching · A-007-004-003
The feed point in a centre-fed half-wave antenna is at the point of:
- Amaximum current
- Bminimum current
- Cminimum voltage and current
- Dmaximum voltage
Correct answer: A — maximum current. From the official ISED question bank, verified word for word.
Why
In a centre-fed half-wave antenna, the feed point sits right in the middle where the electrical current flows most strongly, making it the spot of maximum current. The full explanation — and one for every question — is in Pro.
