Hey Brett,
  You probably know anything between the tuner and the non-resonant antenna 
is going to have LOTS of swr and a widely varying impedance.  This is fine 
for open-wire-balanced feedline.  Normally you would NOT want coax-cable 
anywhere in that link.

  That said, if it works for you and you are pleased with the performance, 
that's what really matters in the end.
