I have done some tests with a horizontal loop and putting a reflector 
underneath... Also, one year we had Field Day at my place and had an 80 meter 
horizontal loop at 35 feet with a reflector loop about a foot off the ground... 
Opening and closing the reflector loop had an impact on how well the guys felt 
the loop was getting out... Using the loop on 40 meters there was significant 
improvement with the reflector loop circuit closed...
  We need to remember that the reflector will partially screen the ground 
directly underneath from 'some' of the current flow... It will not measureably 
change ground induced current loss in the near field beyond the immediate areas 
under the reflector...
  The bottom line in my mind is that a reflector will help, it will not hurt... 
The degree of improvement is subject to many variables..
