[Elecraft] LDG antenna tuner with 132 foot balanced dipole similar to a G5RV antenna

[hawley, charles j jr]

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 recently bought an LDG AT600 Pro Automatic Tuner.

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.
