A few years ago I took a cue from a usenet posting by Walt, W2DU, that stated that the 102 foot doublet of the G5RV is a good antenna on 80m when fed with twin/window lead and a tuner as it is 3/8 of a wavelength on that band. I carried it further and have a 204 foot doublet fed with 450 ohm window lead and a Palstar AT1500DT tuner and the apex around 40 feet above ground level and the ends around 20 feet.. It may or may not work with the K3's internal tuner as I've not tried feeding it with coax. It works very well for me on 160m, 80m, and 40m. At the moment I am also feeding it on the higher bands until I get dedicated wires up for those bands.
As I understand it, the 3/8 wavelength on the lowest band avoids feeding it at the voltage loop so matching is easier. Having a 3/4 wavelength 80m and 1.5 wavelengths on 40m also matches easily in my experience. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds.
