If you use a rather long coax feedline, the K2 tuner might match it. Reason: 
The coax acts to reduce the "apparant" SWR by inducing considerable power 
loss. The 43' vertical is recent fad and it makes no sense at all. Virtually 
any trapped multiband vertical should easily outperform it. If you want to 
find out how it works, just run 43' for wire up a pole or a tree limb and 
see. Do this before investing $300 in a stick of aluminum.
Also, you may be subjecting the little components in your K2's tuner to high 
currents when attempting to match that 43' stick on 80 and 160 meters. 
Impedances would be insanely low! Recommend using a remote tuner at the 
antenna's base, forget the so called balun/unun or a different antenna. 73
