222, I attached below 4 pages of the book "Reflections II" by Walter Maxwell, W2DU.
IMO this might help explain how line length effects a working feed line.
With this said, there are distinctions to be noted in these words that should not be ignored. So be sure and watch and try and understand the exceptions also noted for these rules.
IMO we see here that Maxwell correctly gives us something on the one hand and takes it away on the other. I think this resource is the kind of stuff that CB ideas are often taken from, but I sometimes sense the full text is not always fully considered in the reading, so we often just get CB BS instead.
222, I haven't been convinced yet that we need to use a 1/2 wave line for tuning or for a working feed line. It is my opinion we will likely see as good match using any other random length line. So, IMO line length matters little.
I read Maxwell's information here to suggest there might be detrimental issues using a resonant tuned working feed line...Common Mode Currents on line I3 in the attached image. 222, maybe you can test this idea and post your results.
So, I ask this question, if we are tuning a new antenna and the load is not matched to the feed line showing a mismatch, what will a tuned 1/2 wave feed line in this case show us that a random feed line won't?
I don't know if the following is real scientific theory or not, but I've always been lead to believe...that any length of a working feed line will look transparent (show a perfect match anywhere along the line and at the radio end of the line, if the antenna match at the feed point is resistive (prefect) at the frequency of choice.
The only exception for this is some attenuation...due to resistance and added line length. Again, read about this specifically in the attachment below in the first paragraph of Section 21.3 the first page. Better still read it all, over and over.
These are my opinions.
