[Elecraft] "random wire" and the KX3 ATU

In fact what you can do is just make the first 17 feet of the antenna (including counterpoise) out of ladder line or even twin lead so that
it is a zepp fed W3EDP. This is what I use as my low-band antenna at home and my backup antenna at the cottage. Through a 4:1 
balun I am able to get a good match on 160m through 10m with the internal tuner in my K2 and my LDG auto-tuner. 
It works .. I even made a few 160m QSOs with it running 5W on CW during field day.  I find that it is easiest to erect as an inverted-L.

>That length is close to the W3EDP antenna length - as I recall, it is 86 feet for the radiator and 17 feet for the counterpoise wire. 80 through 10 meters is good, and the KX3 tuner will match it easily.
