What is the advantage of locating an antenna tuner near the antenna feed point, over locating it near the transceiver?
- AMore usable bandwidth
- BLess transmission line loss
- CMore harmonic suppression
- DLess atmospheric noise pickup
Correct answer: B — Less transmission line loss. From the official ISED question bank, verified word for word.
Why
When an antenna tuner sits near the antenna, it matches the impedance right at the source, so the feedline carries a clean signal with minimal reflection. The full explanation — and one for every question — is in Pro.
