Paul,
I run an EARCHI Matchbox with 44 feet of wire.  It is resonant on 20m (no tuner) and the SWR is below 3.5:1 for the frequencies between 7 MHz and 25 MHz so you can tune 40-12m.  I have no problem tuning it with my KX3 ATU.  I am not sure the KX1 ATU will handle it but I am thinking it does.  The EARCHI matchbox is good up to 100 watts - so it is both versatile and robust.  I have gone to this antenna instead of the PAR 40-20-10.  It also tunes 30m and has been my go to antenna for 30m for a long time at my QTH.  It cost $35 to build with a kit from EARCHI and takes about 10 minutes.
