Sorry Karl-Ron had it exactly right.Feedline length is always a 
potential factor; I've run into it before and just forgot.Both with 
coax and ladder line sometimes you have to add or subtract a bit for 
impedance mismatch. You can look it up in the ARRL handbook In fact, 
you can even do a fair matching job with ladder line bypassing a 
tuner with the correct lengths.I added two feet of feedline and it 
loaded right up sweet as pie. I also should have realized it wasn't a 
shorted feedline as it still took some power and signal strengths 
were not hugely different as when there's nothing connected.
