Quad Antenna - The E-Z-O Variation

The E-Z-O Variation

In 2008, Daniel Mills, N8PPQ, designed an antenna that may be an improvement over the quad design. His E-Z-O antenna uses flexible dielectric tubes rather than rigid poles to support the electrical elements. He claims slightly higher gain over the quad due to its roughly circular form.

The magnitude of the dielectric effect on the outside band elements was surprising. Experimentation was required to establish optimum element lengths. Referencing literature was not to be found. As reported at http://personal.ee.surrey.ac.uk/Personal/D.Jefferies/antennexarticles/diecon.htm, "As far as we are aware, there has been no reported work on encasing loop antennas in dielectric."
