Cecil, rather than help people with questions and give them good
helpful answers you seem to just want to turn it into a peeing contest.
Even if you have to drop sentences to make it appear someone else is
wrong.
Pot: Kettle, Kettle: Pot.
This was a deliberate dose of your own medicine. When you
stop the deliberate obfuscation of my postings, the problem
will cease to exist.
That's not true.
You interact with others through obfuscation and bullying. I just wish
you could control it a little bit becuase you do have useful things to
say. Sometimes people want answers to questions Cecil. The J-pole is a
good example where the focus should be on the antenna.
All of the models I've found on Cebik's site and nearly all of the
models elsewhere lack a ground or mast connection at the shorted
feed-stub junction, while most J-poles have that connection. They also
use a floating ground independent current source, which virtually no
J-poles have in the real world. I'd bet nearly all J-pole are
eventually fed by unbalanced feedlines or feedlines with finite common
mode.
The models, through pure accident or lack of basic understanding, use a
BEST case feed simulation that masks all of the problems a J-pole has
with common mode current.
No designer in his right mind would use such a lousy feed system to
feed a pattern sensitive design like a Yagi antenna, they are barely
acceptable as a omni-antenna.
