George,
I agree 100 percent with your analysis. That being said, I've never seen a
real world situation where the SWR that you read didn't change when you
changed the coax length. It makes me think that the SWR meters we have are
only rough approximations and don't really computer SWR properly. Also, I
think currents on the outside of the coax shield are more prevalent than we
think. This current could be a major contributor to SWR changing when the
coax length changes. Anyway, it's an interesting discussion. The
theoretical verses real world does seem to be misaligned in the SWR case.
