MMANA Disain Antenna

MANA is an antenna analyzing tool based on the moment method introduced in MININEC (Mini Numerical Electromagnetics Code) Version 3. MININEC should not be confused with NEC, which is a large antenna analysis program written in FORTRAN and designed to run on main-frame computers. Early versions of MININEC were written entirely in BASIC and the computation engine source code was published as a PDS in MININEC Version 3. That BASIC source code was ported to C++ and compiled to provide faster and more memory-efficient computer execution. A graphical user interface also was added that makes MMANA much easier to use than MININEC version it was ported from. (Some portions of later versions of MININEC are written in FORTRAN.)

Most professional antenna modeling is now done with later versions of MININEC that have important improvements. However, Version 3 has one big advantage compared to later versions. It costs you nothing! Furthermore, even though it is outdated, its capabilities are adequate to model most antennas commonly used by amateurs.
