[Elecraft] [KX3] Field antenna tip

[Wayne Burdick]

Like this, but just the "hot" wire (the one up in the air). The counterpoise wire was used as-is, with no ad-hoc inductance in series.

Normally the ATU (KXAT2) can handle just about anything, but this particular combination of lengths wasn't working well on 40 m; SWR was still around 3:1 after matching. It probably looked like an end-fed half wave to the tuner.
