"correct" reading????? what do you mean "correct"???
if a meter @ the feedpoint reads "X" vswr, and part of "X" is due to a non-resistive load" then a meter 1/2 e wl away will also read "X" vswr. meters are "dumb", all they do is make a ratio.
I already talked about non-resistive loads at the feedpoint in a prior post.
the POINT is that, in the example I gave, is that the VSWR at the feedpoint will NOT change due to any changes in the feedline prior to it.
add or remove coax all you want before the meter @ the feedpoint, and the meter at the antenna feedpoint should not change.(unless you have a coax issue).
therefore , addition of feedline does not change the ACTUAL VSWR , you may get a different reading if you have the meter in the WRONG location, but, the ACTUAL VSWR still hasn't changed.
you guys missed the most important part of the post:
bottom line: only antennas produce VSWR.
feedline does not produce vswr (unless it is damaged or it is designed to radiate).
