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.
