Help me to find out that which book intruduce J pole antenna

Hi, friends,
would you please help me to find out that which book intruduce J pole antennas, thanks.

There is a good article in the March 2007 issue of QST.

This is such a specialized antenna type that I have never seen it described in an ordinary engineering book. Try a ham radio book.

J pole antenna, it sounds very interesting, who can share some materials with us.. thanks in advanced.
