I have heard you mention doing everything except getting rid of that tuned
length line.  I would reset the elements to the mfg specs, and get another
line (NOT the same length) and try again.  Every good null you have is at a
multiple of the 7.15 where the coax is a half wave. This has to mean something

Good luck
