What SWR results from connecting a 50-ohm feed line to a 200-ohm resistive load?

4:1.

  1. 1:4
  2. 4:1 ✔
  3. 2:1

Why: For a resistive load, SWR is the larger impedance divided by the smaller. 200 divided by 50 is 4, so the SWR is 4:1.

Huh, didn't know that: A 50-ohm feed line connected to a 10-ohm resistive load gives an SWR of 5:1.

Answer: 4:1. For a resistive load, SWR is the larger impedance divided by the smaller. 200 divided by 50 is 4, so the SWR is 4:1.
