Evidentally you have been misinformed; A coaxial stub does not have to be an electrical quarter wave length.
And if you bothered to think this through you would realize the error of your thinking
A shorted 1/4 wave stub would theoretically present an infinite impedance at the other end and how that is gonna help correct an impedance match on this antenna when it is in the OMNI mode is beyond me.
I stated that it was a shorted stub that was made from RG-58 and it was approximately 9 feet long and you thought it was necessary to indicate that it was a 1/4 stub and you're wrong; It is a stub but it ain't a 1/4 wave.
If it was a 1/4 wave stub of RG-58 it would be nearer 6 feet at CB frequencies.

Do you really think that "approximately 9 feet" is close to 6 feet.
I am pretty sure that if it was supposed to be a 1/4 wave stub then they would have said "approximately 6 feet". (assuming RG-58)
Are you really having that much trouble understanding this?
