It appears the current distribution of the Franklin is such that current 
maximum appears at 90 and 270-degrees above the ground.  If that is the 
case, the ground system would function just as it does with a half-wave or 
190-degree radiator -- meaning that it is still necessary, but is 
considerably less ground-dependant than a radiator of less than 180 degrees 
in height where radiation resistance becomes increasingly dependent on the 
quality of the ground system beneath it.
