Well...maybe the component sizes in the automatic LDG design are coarse enough that your 1:1 values of components is not acheived. Of course a manual tuner has infinite values of continuously variable capacitor and inductor values. Thus it's easier to acheive 1:1. But anyway, why worry about 1.8:1? And how are you measuring SWR? Accurately? So many variables, and 1.8:1 not mattering, I would forget any concern about it.

I seem to be able to get a low VSWR on 80 & 40 meters, but on 20, 15, & 10 meters the best it will do is ~ 1.8:1. My "G5RV" (It's really a Van Gordon 80 meter all bander fed with 450 ladder line, 33 feet long, and then transitions to coax thru a 1:1 choke balun; coax is ~ 6 feet long. Has anyone found a configuration that works better on all the bands? Previously I have been using an MFJ 962D manual tuner that is able to tune down below 1.2:1 on all bands.
