| Yes....  so,  I try my question again:  Why does he need a balun? Why 
not just connect the tuner to the feed line and skip the balun ? 
Here is why I ask:  The tuner will take itself off line whenever SWR 
exceeds some threshold and power exceeds 75 watts.   As the inquisitor 
said, he must cycle the unit off-and-back-on to resume or restart the 
tuning function. 
Let's just assume for a moment the problem is NOT  CMC on the window 
line...  why not just remove the 4:1 balun and see what gives? 
I hope this is no misplaced, but a serious application of Occam's Razor 
suggests to assume no balun is needed between the device and the antenna 
elements.   Why presume CMC or other problems ?   Why not just remove 
the 4:1 transformer and see if it tunes without it? 
That worked in my case.  Less is more, sometimes.
Any traction?     Now where is my Teflon suit...       ;-)       ;-)

My take is to bring the balanced line all the way inside to the tuner.
