ARRL Periodicals Index Search - This database contains the QST index from 1915 to the present and the QEX index from 1981 to the present. For QST issues from 1970 to the present, and some selected articles back to 1922 (when construction articles featuring tubes began in earnest), identifying keywords have been added to the technical articles. By entering keywords (ANTENNA) or combinations of keywords (CONSTRUCTION ANTENNA VERTICAL HF) into the Title words: field, you may create dynamic bibliographies.

Wayne N6NB invented the Quagi, an easy to build cross between a Yagi and a Quad. The ease of obtaining parts has made this a popular choice for thousands of hams.
- The Tiny 2
The "Tiny 2" is a great little 2 meter beam. It has some really interesting properties and it is a fantastic first time antenna project for the beginner.
- The Tiny 2+1
Renamed the Tiny 3. As with any standard three element design, this three element direct connect antenna utilizes a reflector and a director to achieve gain.
