Correction below...I MEANT to say;

Top loading will cause the BASE current to be higher because of higher
radiation resistance and improve radiation efficiency!

ALSO top loading is better than anything else on the vertical side to raise
radiation resistance and improve radiation..but the gnd has to be there
1st...NO, doing 1/2wave electrically will NOT work...(only way it will is
raise the vertical to minimum 1/4wl physical height and then add 1/4wave
electrically through loading or coils...but WHY?? 1/4 wave is easy to match
and offers decent radiation)
