It is indeed true that line loss can increase dramatically when a line is
not matched. The quoted loss values are only for a matched line. I have
seen plots of coax (vs. twinlead or open-line feeder) cable loss as a
function of SWR and line length, and the numbers can get quite large. Some
amateur radio operators choose open twinlead rather than coax to feed their
antennas for this reason.
I think you are on the right track, but not sure how to solve it. Accurate
modeling of the coax and a good simulator that includes lossy t-lines, with
skin effect and dielectric losses, might help.
