What is the relationship between high standing wave ratio (SWR) and transmission line loss?
There is no relationship between transmission line loss and SWR
High SWR increases loss in a lossy transmission line✓Ճիշտ պատասխան
High SWR makes it difficult to measure transmission line loss
High SWR reduces the relative effect of transmission line loss
Բացատրություն
SWR by itself dissipates nothing, but reflected power has to travel the line a second time and the standing waves raise peak currents and voltages, so a line that already has loss dissipates more of the energy. On a hypothetical lossless line, SWR would add no loss at all.
