That is incorrect -- if your "SWR Meter" is indeed measuring SWR. The
complex impedance seen by the rig (or tuner) will change depending on the
length of coax, but not the "true" SWR. For an insight into this, read
Chapters 7, 8 and 9 in "Reflections II" by M. Walter Maxwell, W2DU. A most
illuminating book that should be read by every "technically oriented" ham...
