Antenna Modelling For Radio Amateurs Made. Was perhaps my nine month involvement to produce the new revised English Help File with. MMANA-Gal library. Basic library of “antenna parts” and uses these to build new designs. MMANA Antenna Modeling Program Author. Computer Antenna Modeling Simplified. MMANA-GAL Antenna Modeling Program Author: Makoto (Mako) Mori JE3HHT © 1999-2000 Gontcharenko Gary DL2KQ-EU1TT developed and released English versions of MMANA in 2001-2002. Nobuyuki Oba JA7UDE wrote an English user manual in 2001. Software beta testing was provided by a group of fellow amateurs. Mmana Gal TutorialM 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. Hp san expert tool download. Signs Spearfish, SD| Custom Sign Business.

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 Furthermore, even though it is outdated, its capabilities are adequate to model most antennas commonly used by amateurs. Mmana Gal Antenna ModellingThe radiation field produced by a transmitting antenna system having any known arbitrary current distribution can be found by adding the separate fields produced by elementary lengths of thin conductors with each elementary length treated as a very small radiating doublet antenna. In adding the contributions to the total field that are made by the individual doublets that can be considered as making up the actual current distribution of an antenna it is necessary to take into account the phase and the plane of polarization of each contributing component field. Those field strength summations can be done by either graphical or mathematical integration. ![]() Many excellent examples of both graphical and mathematical methods appeared in literature printed prior to 1940, for example, F. Terman, Radio Engineering, 2d ed, p. Mmana Gal Antenna Files658, McGraw-Hill, New York, 1937. The MININEC moment method of far field radiation calculation is a mathematical integration method based in principle upon the fundamental concept of summing fields from many small elemental sections of thin antenna conductors that compose an antenna system. How to convert audible files. Information about the moment method of far radiation field determination has appeared in Amateur Radio literature. For example, Hiroaki Kogure, 'Antenna design using PC,' CQ Publishing, April 15, 1998, and Matsuda-san JA1WXB 'Theory and experience of antenna simulation,' Ham Journal No.
