Antenna performance does not depend on how it is fed (if feeder losses are low) but on height and ground type. For KX3 with AT, any special length makes little sense, especially in portable conditions. KX3 matches most random wires, and KX3 with 4:1 balun matches any wires. Lack of balance is not too important with battery operation. I try to make random wire + counterpoise at least 1/4 wave on the lowest frequency for reasonable efficiency.
For 1.5 KW, an endfed with a 49:1 or so transformer makes lots of sense as wideband tuners for QRO are rare, expensive and heavy. "Myantennas.com" perfected a transformer that has very small losses and does not self-destroy at high power. But in inv V configuration, it is way down from a flattop.
