These pages will present a short guide to antenna optimization using MMANA-GAL. This program has a very complete optimization engine, which is unique for free software. (The amateur radio community seems to have focused on the EZNEC software, which is lacking in these abilities.) The first part is an overview of the process, using a 3 element. MMANA-GAL is an antenna-analyzing tool. On I am working on this website. The intention is that source codes of various antennas will come in for the radio amateurs. There are now only a few examples, but there is still a lot of fun stuff. So register at the bottom of the 'FOLLOW blog via mail page'. The same with Vertical Antenna design principles. If You need repeating Watch, better download it with highest resolution possible. By Roosdiarto Rooskandar. MMANA-GAL is an antenna-analyzing tool based on the moment method, which was introduced in MININEC. If you do not know this program yet, try it. It is interesting. In video the simplest example of.
4NEC2
4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style
antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced
antenna modeler.
When running frequency sweeps, linear or logarithmic style SWR, Gain, F/B-ratio and impedance line-charts are produced. With the
included Optimizer and Sweeper one is able to optimize antenna- and/or other environment-variables for Gain, resonance, SWR,
efficiency and/or F/B, F/R-ratio. With the sweeper one is able to graphically display the effect of changing one or more of these variables
for a specified range of values/frequencies.
For the starting modeler agraphically based 3D geometry-editor is included which requires no additional NEC knowledge while still
enabling you to create and visualize and compare current-distribution, far/near-field patterns and Gain/SWR charts. More experienced
modelers can use the gradient style and/or the genetic algorithm based optimizers to improve their designs.
