GAL-ANA

Professional antenna software

         Demoversion NF-viewer (8,3 MB) is ready. This is a new window "Near Field" of the GAL-ANA.

• 1. Download it.
• 2. Run NF-GAL_ANA.exe
• 3. Open (File > Open)  *.nfd file (examples of the near field).

• There is no help file yet, actually we just count on your sanity and natural curiosity, as well as intuitive clear interfaces.

 

Info 19/12/2008

               Window 3D far field help is ready.

 

Info 31/03/2008

               Demoversion of GAL-ANA 0.3 is ready. It is not a full version, we still work on that. But you can download it and try now. We just would like to present the users some features and windows released by now:

• 1. Calculations are performed in MININEC3 and  NEC2 engines.
• 2. 2D far field window is available. Polar and Cartesian coordinate systems can be applied, with any scale or off scale at user's option.
• 3. 3D far field window, as well as color/monochrome 3D surfaces/grids, flat sections, projections and slice.
• 4. Near field window  (at this stage in NEC2, only) can now be displayed along with color 3D surfaces/grids and flat curves of distribution of reactive zone.
• 5. Move-Rotate window is available.
• 6.  A small built-in explorer is available allowing a quick preview of an antenna image BEFORE the program opens a respective file.
• 7. Tabs of the lines and networks are presented in the main window.

• There is no help file yet, actually we just count on your sanity and natural curiosity, as well as intuitive clear interfaces.

   The demo version GAL-ANA 0.3 allows opening and calculation of any *.gaa files any antennas' models available in the DEMO_ANT directory, though the files cannot be edited. In the meantime you can create, edit and calculate your own *.gaa files and open any *.maa and *.nec files.

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

 

 

Info 18/10/2006, update 02/03/2008

               ... yes, we are making a new antenna modeler. It is not ready yet (a lot of work has been done but still quite a lot to do), but the Alpha-version already exists and works. Therefore we suggest, it is possible to acknowledge it to you. This is the logo:

List of the features of GAL-ANA

• Engines: NEC2 and MININEC3 (which is much preferable than NEC2 in many cases) with a possibility to toggle them on the run. In the future (not quite soon, but still) there will be a chance to use the external NEC4 engine which you would have to purchase separately.

• An independent direction diagrams' window with a possibility to show flat and 3D diagrams in Polar and Cartesian coordinate systems, with any scale or off scale at user's option. Digitizing, as well as scales on 3D diagrams. A vector (user movable measuring point) on a 3D diagram.

• An independent nearby field window. 3D surfaces and flat curves of distribution of reactive zone.

• An independent graphs' window. Draw of any user defined graphs. Values to be allocated along X and Y axis, their limits, scales, number of points of calculation, everything is user defined. It is possible to build analytic 3D graph-surfaces to watch two simultaneously analyzed parameters.

• An independent antenna edit window. If you are acquainted with MMANA-GAL, these are substantially supplemented and improved "Edit wire" and "Edit element" windows with more tools to edit an antenna description. Among numerous options we shall only mention a possibility to operate under groups of selected wires, as well as user adjusted generators of complicated curves and surfaces (helixes, cylinders, paraboloids, etc).

• A graphic window of presentation of nearby (reactive) field including both flat and 3D view. One can see the nearby zone and evaluate what it covers upon.

• An explorer of files' preview. It allows to quickly look through several tens of files and eventually pick up the one liked. It can be done BEFORE the program opens a file. The work with large directories of antennae files turns to be tens times faster and much more comfortable than usual. It allows to look through several files a second.

• A graphic window of set up of a complicated ground. A 3D cut immediately shows a side view of user defined ground. Different layers are shown in different colours.

• A possibility to look for antenna file in such files' directory under user defined criteria. A possibility to record (and a further quick pick up) of several various complex ground structures.

•  A possibility to set up different materials for different wires.

• A possibility to define some wires as isolation covered.

• A pre-installed set of standard optimization scenarios. For example, if a Uda-Yagi antenna is to be optimized, necessary set ups are made by application of a corresponding scenario from a menu which is done by a few mouse clicks.

• All set ups, including ground and optimization, are recorded into the antenna file.

• A large independent Tools' window with all necessary matching units, multipart matching units made out of sets of lines. A window of synthesis of systems of feeding of active antennae.

• Print of all results under user defined printing requirements.

• A large window of general set up fully user defined, i.e. lists of frequencies, hights, cables' types, wires used (diameter, material, isolation), complex grounds, etc.

• Several small constantly activated windows of working tools such as rotation, move, quick edit of a separated wire, quick insert of sources/loads into a certain place, etc. Hence all this works not only with the Edit window activated, but also with other windows, such as Antenna view. These windows substantially increase speed of minor quick antenna correction.

• The Antenna view window provides an ampermeter allowing to measure current in any defined segment.

• Several other minor (and not only) features allowing to build and understand antennae.

   Please don't ask when the program will be available. We still keep on working on that and woud like to know ourselves when it's ready... Programming is a process laying behind any planning. Any news on the work status will show up at this page.

*The program is not yet ready completely. We still work.
