Demo-version of GAL-ANA 0.4 is ready. It is not a full version, we still work on that. But you can download it and try now.

Sep 02, 2020  Library Of Mmana Antenna Files. The performance of the antenna, through the model, will be explored in several typical settings. NEC Corporation today announced analysis results from efforts using AI prediction platforms to design blueprints for SARS-CoV-2 vaccines that can drive potent T-cell responses in the majority of.

  • The demo version GAL-ANA 0.4 allows opening of any *.gaa files any antennas' models (over 1500 files) available in the ANT directory, in the GAL-ANA online library and of any .maa and .nec files.
  • You can create, edit, calculate and save your own .gaa files1.
  • The demo version GAL-ANA 0.4 allows calculation of .gaa files any antennas' models available in the DEMO_ANT directory and in the GAL-ANA online library, though the files cannot be edited. Also you can calculate .maa and .nec files1.

The demo version GAL-ANA 0.4 has a few new windows (f.e. Tools), online help2 and built-in library (over 1500 antennas' models files). Click the picture below to save the setup of the demo version GAL-ANA 0.4 to your computer:

1. The demo version is restricted by 4 wires, max, in MININEC3 and 40 segments, max, in NEC2 engine for a user's .gaa file and for .maa and .nec files.

2. The help files are not full complete yet, actually we just count on your sanity and natural curiosity, as well as intuitive clear interfaces.

GAL-ANA and antivirus programs

It is well known that antivirus programs may be overly sensitive to some executable files and programs. GAL-ANA is not an exception and from time to time we receive reports on likely virus-positive reactions from some antivirus programs to the GAL-ANA installer. In this regard we would like to state that we do our best in order to shape our program the way it does not look suspicious for antivirus programs, and obviously we do not allow real viruses to penetrate into our program from outside. Our program is too well built and controlled by the crew to allow that. However, it is very difficult to follow changing algorithms of antivirus programs as they evolve. Therefore we cannot guarantee a full absence of false positive reactions of some antivirus programs to our installer.

  • We declare herewith that GAL-ANA does not contain any virus and the likes.

Please take the above into consideration and if your antivirus program alarms at GAL-ANA, you may either contact the customer support of your antivirus and let them settle the false positive reaction, or just use another well proven antivirus program. F.e. Avira is one of them.

Antenna Design Software
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 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.

The 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. E. Terman, Radio Engineering, 2d ed, p. 658, 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.

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. 95, CQ Publishing. However, those two examples are written in Japanese and are believed to be available only in Japan.

The mathematical calculations required to perform far radiation field integrations are complex and laborious to do manually, but MMANA uses an improved (faster and requiring less memory) MININEC computation engine to do the work for you. You can simply describe an antenna, or load an antenna description file someone else has created, click a Start button, and MMANA will calculate and plot the vertical and horizontal far field radiation patterns of the antenna for you. It also will calculate the feed impedance, feed-line SWR, bandwidth, and other things.

However, the 'Garbage In, Garbage Out,' rule applies especially well to MMANA and other antenna modeling programs. Fail to describe an antenna properly or ask MMANA to do something that is beyond its capabilities, impossible, or stupid and it will give you either no results or misleading results. MMANA is a very capable and valuable tool if used correctly, but like with most sophisticated tools, correct use requires a certain amount of understanding and care.

MMANA-GAL Antenna Files Library
Gary, DL2KQ-EU1TT, maintains a Library of MMANA-GAL Antenna Files that all MMANA-GAL users should know about it, because it contains a wealth of antenna designs that can be used as-is or modified to suit individual needs and experimental curiosities.
