Ofcourse even optimisation is not new to antennas
which is why the program is offered for free to
amateurs.

Unfortionally however, it uses the old MiniNec 3.13 engine. Those
interested in antenna modelling should know the drawbacks and pitfalls
as compared to then Nec2 or Nec4 engine used by EZnec and others...

Do you know of a program that for optimisation can work with all
dimensions being variable
AT THE SAME TIME?
At the moment I am confined to using a number of variables in a
antenna array
until the objective is achieved and then by moving these variables to
the bottom of the list
it allows me to work on the next series of variables and so on until
acceptability
is obtained for the whole antenna array. Doing this takes a very long
time when each line
or wire comprises of seven (7) variables even with a high speed
computor.
