Library Of Mmana Antenna Files
MMANA-GAL Antenna Modeling Plan Writer: Makoto (Mako) Móri JE3HHT © 1999-2000 Gontcharenko Gary DL2KQ-EU1TT developed and launched English versions óf MMANA in 2001-2002. Nobuyuki Oba JA7UDE had written an British user manual in 2001. Software program beta testing was offered by a group of associates amateurs. Michael MANA is usually an antenna analyzing tool centered on the instant method launched in MININEC (Mini Numerical Electromagnetics Code) Version 3. MININEC should not be baffled with NEC, which is definitely a large antenna analysis program written in FORTRAN and created to run on main-frame computers. Early versions of MININEC were written completely in BASIC and the calculation engine supply code had been released as á PDS in MlNINEC Version 3. That Fundamental source code had been ported to D and put together to supply faster and even more memory-efficient pc execution.
A visual user interface also has been included that makes MMANA significantly less difficult to make use of than MININEC version it has been ported from. (Some servings of later on versions of MININEC are usually created in FORTRAN.) Most expert antenna modeling is definitely now performed with later on versions of MININEC that have got important enhancements. However, Version 3 offers one large advantage compared to later on versions. It expenses you nothing! Furthermore, actually though it can be outdated, its features are sufficient to model almost all antennas frequently used by beginners.

The light field created by a sending antenna system having any recognized arbitrary current submission can end up being found by incorporating the separate fields created by primary measures of thin conductors with each elementary length taken care of as a really small radiating doublet antenna. In including the contributions to the complete field that are usually made by the specific doublets that can become considered as producing up the real current submission of an antenna it is definitely necessary to take into account the phase and the plane of polarization of each adding component field.

Those field power summations can end up being done by either graphical or numerical integration. Many excellent examples of both graphical and mathematical methods appeared in materials printed previous to 1940, for example, N. Pdf to excel 3.1 serial key. Terman, Stereo System, 2d ed, p.
658, McGraw-Hill, New York, 1937. The MININEC instant method of much field rays calculation is a numerical integration technique based in concept upon the essential idea of summing fields from numerous small necessary sections of thin antenna conductors that create an antenna system. Info about the second technique of much radiation industry determination provides appeared in Amateur Radio materials. For illustration, Hiroaki Kogure, 'Antenna design using Personal computer,' CQ Posting, Apr 15, 1998, and Matsuda-san JA1WXB 'Concept and experience of antenna simulation,' Ham Journal No. 95, CQ Posting. Nevertheless, those two illustrations are composed in Japanese and are usually thought to become available just in Japan.
The numerical calculations required to perform far light industry integrations are usually complicated and repetitious to do by hand, but MMANA utilizes an improved ( quicker and requiring less memory space) MININEC calculation engine to perform the work for you. You can just describe an antenna, or load an antenna description file someone else offers created, click a Start key, and MMANA will calculate and piece the straight and horizontal far field radiation designs of the anténna for you.
lt furthermore will compute the give food to impedance, feed-Iine SWR, bandwidth, ánd some other things. Nevertheless, the 'Trash In, Crap Out,' principle applies specifically properly to MMANA and some other antenna modeling applications. Fail to explain an antenna correctly or ask MMANA to do something that can be beyond its features, impossible, or ridiculous and it will give you either no results or misleading results.
MMANA will be a really able and beneficial tool if utilized correctly, but like with many sophisticated equipment, correct make use of requires a certain quantity of knowing and treatment.
I provided a chat on antenna modelling making use of the free of charge MMANA-GAL software program at my local Amateur Radio stations Membership. It appears at what MMANA-GAL is usually, how to use it and after that a quantity of various applications. Some of these are helpful and unexpected - like how to optimize a 40m off center given dipole (Windom) therefore that you can obtain 15m. And how mounting an antenna as an inside-out Sixth is v can seriously modify its radation design or number of rings obtainable.

It furthermore requires the query is definitely the G5RV actually a good multiband antenna? Why had been my W3EDP finish fed much better to the sóuth-east and south western world and rotten to the northern.

And does thé DL7PE Microvert radiaté off its féeder? With the records included (8.8Mw). Notice: I have also produced accessible a Zip document with some.maa files including the End fed Fifty percent Influx, Rybakov up and down, DL7PE Microvert, 80cm magnetic loop, 65ftestosterone levels Inverted L, EH antenna, 20-15-10m capture dipole, 80m OCFD (Windom) and an experimental W5GI mystery antenna document. Hi Marko, The usual way is usually to generate an eight-sided octagonal cycle. I believe there is certainly an 80cm diameter one in the good examples with MMANA-GAL.
