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...

There are many view as what is advantageous and what is not.
In the early days I compared mininec and NEC programs both of
which had pitfalls that you had to be aware of and that really
was the key in achieving most for what you bought. To me EZNEC
is for people who like crossword puzzles in that the progam
tells you that what you have is no good. Where as the other
program puts out a helping hand to show the direction changes
that are needed for success and frankly the majority of program
users need more than the realisation that what they have
designed is no good. It is like the carrot and the stick aproach,
if a bite of the carrot seems implausable you stop trying to
bite and put the program away Now we have NEC programs that
posses optimizers that older programs such as eznec e.t.c.
cannot supply but with the increase of availability of newer
programs such as yours the cost becomes a powerful motivator
such that the modern programs which are more than suitable for
a amateurs needs are now available, for free no less.
To have a program that meets all my needs for the cost of nothing
carries much more weight than owning just a calculator or a
slide rule of yesteryear. True there are many users of the eznec
computor programs by those who purchased many years ago many
of which have tired of it but for a person at the entry level
to fork out hundred of dollars for an antique when he can get
more for free and keep his money to me there is no argument
At the same time should we not inform newcomers to the hobby
of the pitfalls that could delusion those who we need so badly?
