Part of subelement G9 — ANTENNAS AND FEED LINES, which contributes 4 questions to every exam across 4 groups.
Lessons covering this
- Feed Lines and SWR, Computed11 min
Compute SWR from a resistive mismatch, say what sets a line's characteristic impedance, and explain why line loss flatters an SWR reading.
