Question 361

What standing wave ratio results from connecting a 50-ohm feed line to a 200-ohm resistive load?

  1. 4:1Correct answer
  2. 1:4
  3. 2:1
  4. 1:2

Explanation

For a purely resistive load the SWR is the ratio of the larger value to the smaller, here 200/50 = 4, giving 4:1. SWR is always expressed as a number of one or greater, so 1:4 is not a valid form.
