The tuning adjustment at the matching device will be more cricical, since 
you will be running over a full wavelength of tuned feedline.  A given 
change in frequency will move the current /voltage points along the feedline 
a greater percentage of a wavelength than if the feedline were only a 
quarter wavelength or less.  You will not be able to QSY as far without 
retuning.
