Hello Roy,

Tnx for advices;
I Have tried automatic "tapering" With a good convergence, but with the same
results.
I have no other modelling software, so I can not verify if it is due to
MMANA;
if anybody has the possibility to test a GPA in free space with another
soft, I should be interested by the results.
Vertical element 10.6m
radials 10.6m at 90°
radius 1.5mm
freq 7.06 MHz
