The KAT1 will not handle the high impedance of an EFHW antenna. If you want to use an EFHW with the K1 have a peek at the SOTA Tuner that Hendricks QRP sells .. I think that the kit is only something like $35. You can however use an endfed wire that is not a 1/2 wavelength. The recommended 24 to 28 ft length worked against a few 16 ft radials will work quite well on 40m through 15m. I have also had pretty good luck with an end-fed 51 ft wire for 40m/30m/20 although that is a bit too long on 30m and results in at best about a 2:1 swr on 30m unless you coil up a few feet. If you have the space, an 86ft end-fed will will match pretty much anywhere from 80m through 10m with the KAT1 as it is a "magical length" that isn't close to a 1/2 wave (or multiple) on any of the HF ham bands.
