What standing wave ratio results from connecting a 50-ohm feed line to a 10-ohm resistive load?
Pick an answer to check it.
Answer: D. 5:1
For a resistive load, SWR is the larger impedance divided by the smaller: 50 / 10 = 5, so 5:1. SWR is always written with the larger number first.
Tip: SWR = big ohms / small ohms.
