A couple of years ago I downloaded Version 3.0.0.31. It was great fun to re-evaluate my understanding of some simple electromagnetics.
However, my real reason purpose for MMANA was to confirm my thoughts on an inverted -V dipole that I had planned to erect. Again, great, I produced far field polar diagrams for it's half-wavelength frequency (7MHz) plus 10 and 14MHz. At the time, I took a 'screen grab' for each and inserted them into a Word document. (Interesting antenna - because of it's configuration (strong Vee and close to the ground), it has two strong 'dipole like far field polar diagrams', one for horizontal and one for vertical polarization.)
Now, after using the antenna almost daily, I would like to raise it's height by a metre. So, to give a better scaling size for the comparison, I thought to print it's far field diagrams.
Hello
, the prints threw me - because the lobes had changed (geographically). Then, on the print (be it a pdf, or hard copy - or portrait or landscape) I noticed that the 'x-axis' had changed - from the conventional vector ('across the page' - to the right) to 'up the page'.
On my screen grabs the x-axis was 'as convention' - equals to the right. On my 'saved' web-manual page
http://gal-ana.de/basicmm/en/#13 it shows a screen dump - just like the ones I saved.
I had entered the original antenna data as geographically orientated. My wire is North to South so, what I saw was - what I was expecting - the horizontal polar minima were also N-S (on the screen) .
Assuming there was a 'glitch' on my version I have just downloaded Version 3.5.3.82. Now, I notice that the x-axis on the screen has changed to be also 'up the page'.
I can obviously live with the x-axis 'up the page' - by re-entering my data. However as an observation, it seems that MMANA does not now align with any data entered geographically (or mathematical convention) - and that with Version 3.0.0.31, it only did so 'on the screen'.
I wonder if any one else has noticed this (change) in orientation ??
Great software though - thanks !!
