What is the relationship between high standing wave ratio (SWR) and transmission line loss?
Pick an answer to check it.
Answer: B. High SWR increases loss in a lossy transmission line
High SWR means power travels back and forth on the line, so more of it is lost as heat in a lossy line. The higher the SWR, the higher the total loss.
Tip: High SWR plus lossy line = more loss.
