Well that's kind of a long story.  on several occations I've read 
towers who's R value but not the J value were available and came out 
with the same R as the PE who previously read it so had to make the 
assumption that the J that I came up with was accurate, and so was the 
bridge.

I have two 916a bridges and have on occasion read the ATU or tower 
with both of them and come up with the same readings.

I would then read the input of the ATU at Fo and adjust it for 50J0, 
which was all I could do on TX's that didn't have a reflected power 
meter.

After I set the ATU input to 50J0 I would tune / load the TX into the 
ATU on the TX's that were tunable.

So far the TX's with fixed outputs (BE AM-1A etc.) have had reflected 
power meters and I use that to tune the ATU on CW for min reflected to 
accomadate the whole tunnle thing that you suggested, which I think is 
a very good explaination for why the TX doesn't like 50J0 at the ATU 
input.
