What is the interaction between high standing wave ratio (SWR) and transmission line loss?
There is no interaction between transmission line loss and SWR
If a transmission line is lossy, high SWR will increase the loss
High SWR makes it difficult to measure transmission line loss
High SWR reduces the relative effect of transmission line loss
