I'm puzzled as to what you are trying to accomplish here.
AFAIK, a half wave loop at resonance is "voltage feed", meaning
the impedance is extremely high.  It is probably a lot easier
to just leave the loop open and feed it at the center point of
the wire as if it were a bent dipole.  Of course if you have omit
the 4th side of this loop, you now have a Moxon dipole element.
Am I missing something here.
