KXAT3 has trouble matching high impedance antennas. No problem matching anything using BL-1, BL-2, or any other 4:1 (or 9:1) balun although for odd impedances the balun may have substantial losses. But I prefer balun than antenna-tuner overheating.
Probably all wire longer than 1/4 lambda radiate nearly all. Vertical above 5/8 lambda start generating high lobes. Horizontal add a few db because of ground reflections but also lobes. Once I made an experiment trying a vertical with a few radials, a random long wire with radials, or two random long wires as a semidipole, all fed by TV ribbon. In all cases, two random wires were the best, often by far, across bands. But setting up a portable vertical is easy, one long wire is hard, and 2 long wire is the hardest. In a nutshell, random wires are fine with exact length unimportant. If tuning problems, use a small balun.
