This view shows the right half of the tube with its spiral feed wire wrapping which extends out slightly over the tube electrode.  The balun and trigger coils are just barely visible in the far left of the picture.  Note the PVC support near the electrode of the tube.  Below the spiral wire you can see the trigger coil wire which connects one end of the trigger coil to the tube electrode.  The trigger coil wire is fastened to the PVC support just below the tube by using a plastic "tie-wrap".  From there, it goes to the tube electrode.
