Steve, Just one clarification - a mismatched length of coax will transform the impedance, but a perfectly matched line will not. Since we calibrate things at 50 ohms, if the coax is exactly 50 ohms and the SWR is 1.0:1, no impedance transformation will exist. But real coax lines are "nominally" 50 ohms, so the conditions of a perfectly matched line may not exist even though the meters tell us it is at a particular point along the line.
