I have the same antenna, the Cobra Ultralite with window line, and 
simply connect the two ends of the window line to an SGC-230 
automatic tuner http://www.sgcworld.com/230ProductPage.html which is 
mounted outside.  I have the tune power of the K3 set to 3 Watts.  No 
balun required.  Works great, 80 through 10.
