WHAT CAN IT DO MMANA-GAL has the following functions :- Enables an antenna to be defined in terms of straight wires (no loops) using xyz coordinates to specify the ends of each wire.

This together with the program being a free download resulted in its choice! The free basic program (version ) can be downloaded from : WHY THE NAME MMANA-GAL The name is derived from :- Macoto Mori (JE3HHT) who wrote the ANtenna Analyser program - which was later modified by Igor Gontcharenko (DL2KQ) and ALex Schewelew (DL1PBD) 4. As a Christmas present, the author received a copy of the RSGB Publication An Introduction to Antenna Modelling by Steve Nichols (G0KYA) which includes a free CD containing the program together with sample antenna designs. The author experienced problems when trying to install 4nec2 and hence its use was abandoned. WHY CHOOSE MMANA-GAL There is a free Demo version 6 of the program EZNEC but although it is the full program, it is restricted to only allowing upto 20 segments for any antenna design which can be quite restrictive. These 3 programs are the most commonly used by radio amateurs. MMANA-GAL on the other hand is based upon MININEC which was written by John Rockway with support from Jim Logan.

AVAILABLE ANTENNA DESIGN SOFTWARE EZNEC and 4nec2 are based upon the Numerical Electromagnetics Code, or NEC, which is a popular antenna modelling system for wire and surface antennas originally written in FORTRAN in the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. 1 ANTENNA DESIGN FOR FREE USING MMANA-GAL SOFTWARE 1.
