Wayne,
What a novel solution! That's one that would never have occurred to
me! Glad it worked!

Subject: [Elecraft] Field antenna tip
Hi all,
This weekend I was using the KX2 with a random length of wire tossed in
a tree and another random length laid on the ground. 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.
The wires were connected to a BNC-to-binding post adapter, suggesting a
simple workaround. Rather than adjust the length of the wire by cutting
or splicing, I simply reeled in a few feet of it and wrapped it around
one of the binding posts, forming an inductor of perhaps several uH.
The ATU was then able to match the antenna on 40 m, as well as the
other bands (up through 10 m).
