An alternative to ladder line is running two parallel runs of coax
(RG-213) with only center conductors connected to the loop and the
radio end center conductors to a balun which solves the unbalanced
issue. The two runs of coax can be taped together.
Two runs of coax will have something like 200-ohms impedance (if I
recall correctly). The shields of the lines do not connect to
anything but do make the line less susceptible to detuning when run
up thru the building structure.
Since you are running 10w with a KX3 and internal ATU, there is less
things to worry about. Of course the balun could be installed at the
antenna and single run of coax to the radio, as Don suggests.
I was going to put up a one WL horizontal 80m loop at one time and
was considering this feed. We moved and the new property is not
conducive to putting up something this large.
