Hello Guys,
Modeling in its primairy stage should be done in freespace...
As that is the only way to illuminate all the other influences.
With that said, in some cases you need to model in "real live"
example are: take off angle/ RF currents along a mast etc.
However those should be classified under "special cases".
And the "modeler" really should express....these special cases....so others with NO knowledge understands how "not" to interpertate them.
As it is easy to "fool".... guys like array solutions sell 1600 dollar CB antennas with 16..17 dB gain..(and they are right...but they add ground gain so you can subtrackt say..6 dB).
The eznec demo program is perfect for handeling small antennas.
Like dipoles, but as soon as the antennas become large (more metal in the air) you should need a version which handles more segmentation.
With that said...4nec2 handels a lot of segmentations..is free...and has the the same limitation that enzec (nec2) has.
MMana is also free has a large number of segmentations...and uses mininec which is in some case more accurate compared to nec2. (eznec/4nec2)
And there are more things to consider..The average gain factor etc.
In my opion it is not wise to "upload" everything...un less you have done your best to make sure it is not interpertated wrong by others....
And the one who does the modeling should be aware there migth be those who are less knowledgable...heck there are those who do modeling...let say....with room for improvement.
Regarding those phase currents thingy..
I am more than willing to help...but what is it you do not understand ?
As i have done quite some effort in the past and i hate when i am unable to explain it so people do understand. (not your fault !!!)
Kind regards,
Henry
ps havnt put that sigma 4 in cst yet...but will come..when time permitts...already 23.30 local again...so off to bed.
