Well Homer, can you tell a little bit by looking at the model and the title...how the model is constructed?
Original model showing a fair pattern but is showing workable skewing that may be hard to detect:
wM = with mast
wISO = the mast is ISO from the antenna
L = Load inside of a square box is a simulation of a choke at the top of the mast. This device is set to 1pF of capacitance in this case.
Worst case model showing a very bad pattern after I removed the choke from the mast:
wM = with mast
nISO = no isolation
I did not code the title to show no load (nL) but I mentioned that I removed the object that simulates a choke.
I understand your confusion. This was not your fault. I did not explain well enough.
I know words get to be a problem sometimes, but this shows why words are necessary, and I do forget sometimes to describe something...and it might seem I take you guys for granted.
If your setup is different from this model, which is not isolated and has no choke...then this model surely does not even come close to your 2-meter J-Pole.
That aside, however, if I understand this antenna...nothing you can do will fix the skewing...that is the question I asked you, just to be clear...can you detect skewing on your 2-meter J-Pole?
Could I have said it in 2 dozen words? It may be possible, but not on my best day this late in life.
