I thought you were checking this SWR with nothing in line but the Meter and DL.   If you have a tuner in line how would you know what the real SWR would be because the tuner/matcher is designed to match the load. Where ever the capacitor and coil was last set it will produce a reading having no relation to the current test.
The antenna should have a resanant point.  you should tune the antenna for this first.   The meter should be as close to the antenna as possible or practical to minimize line effects.

  Hi all:

  On the one hand I got my buddy researching my antenna to death and coming
  up with a theory that my antenna shouldn't have the Unun balun because it's
  not a 4/1 which is what I'm supposed to have.
  Tom assures me that the way I have my antenna set up is just fine and it's
  the coax. Tom suggested I place a dummy load at the end of my coax and I
  should have a flat or very low SWR. If it was high then it was definitely
  the coax. I did just that and the SWR was 30/1 but was able to be tuned to
  flat and held.
  My buddy put my tuner on his wire antenna with 1kw through it with no
  issues.
  Omg the trials. I don't know who to believe.
