Richard thanks for your answer and opinions.
I am not talking abt Lattin or W9INN.
These are things I hear in this thread for the first time.
I am talking abt using 1/4 wave stub as decoupling element
to make a (reduced size?) two band antenna.

This principle is used in commercial antennas like HY-GAIN AT-18
tower vertical and many others, stubs in line with element.
Orr in his antenna book is using orientation, open to center.but in line
with the element
So I am sure the principle works ok, and I was asking abt the different
orientation
alternatives. I understand that you would suggest 90 degree?
But does it really matter?

Designs do work, inventions rarely do. Yes I agree.
Therefore I am not going to build any complex mess where everything is
hanging of everything, just simple one time decoupling the element for
higher fequency.
