>From what I understand the 1530 in Sacramento was built with no ground
radials, as the consultant said it did not need any. At some point the FCC
made them install a ground system-and it made very little to no difference in
their signal.

For discussion...?

There is a belief that Franklin antennas do not need/use conventional, 
buried radials for an r-f ground.  Possibly that might related to thinking 
that, as a 180/180 Franklin is fed across an insulator 1/2 way up the 
structure, it must operate similar to a center-fed dipole -- and a dipole is 
a balanced radiator not needing/using an r-f ground to produce its gain and 
pattern.
