[Elecraft] Random length wire for use with KX3

There is a reason for the 43 foot vertical - alternately the 44 foot 
each side of center antenna advocated by Cebik (SK).  It is not resonant 
on any amateur band and the impedance range can be handled by most tuners.

So if you are putting up a vertical, I would recommend a 43 or 44 foot 
antenna with a 43 or 44 foot radial (or several radials).  If a dipole, 
use 44 feet on each side of the antenna feedpoint.  If you do not need 
80 meter coverage, go for the 22 feet on each side of the dipole.

Sometimes I put both wire ends up high like a V and sometimes I put one wire end up high the other on the ground or just above the ground.  Tuner seems to be able to tune all the way from 80M - 10M.   Sometimes if it doesn't want to tune, I shorten the ground side until it does by coiling the free end of the ground wire.  I've used shorter wires when I only want to work 40M and below with good luck also.  Just get some wire and mess with it until you find something you like.
