History of the VersaTee 60m80m Vertical pdf file


The VersaTee vertical 80m or 60m modular antenna system.

  This modular antenna system offers the opportunity to every ham radio operator the ability to efficiently communicate on 80m or 60m without requiring a large piece of real estate, tall towers or trees. One person can easily setup this antenna in their backyard or transport it to virtually any remote location, and set up in just a few short minutes. Absolutely no need for tall supports this is a completely self-contained system. Unlike traditional low band vertical antennas requiring many ground mounted radial wires this system utilizes a single elevated sloping ground radial.
  Traditional verticals have the feedpoint of the antenna at or very near the ground. With this antenna the feedpoint is elevated to a height of approximately 10 feet above ground, thereby reducing near field ground return losses, it also improves the overall performance and efficiency of the antenna.

  The antenna fits in a space of 35' x 30' for 80m

  The classic MonoPole vertical only develops radiation from the vertical element the radial wires contribute no radiation. In this system the single elevated radial wire actually contributes the majority of the radiation the antenna delivers. The angled elevated radial serves multiple purposes. As the radial wire progressively moves closer to the ground, the takeoff angle of radiation from this wire constantly changes. This measurably increases the range of takeoff angles that have the same amplitude.
  Because the radial wire slopes down from a height of 10 feet to a point 2ft. above the ground, this also raises the radiation resistance to near theoretical maximum . The antenna contains both 70 percent vertical and 30 percent horizontal components. When the vertical component starts to diminish above 45 degrees the horizontal component continues to the critical angle. Because the distance between stations diminishes as the takeoff angle rises, the 30 percent of horizontal component is more than adequate to deliver strong NVIC signal reports.

When the radial wire reaches two feet above the ground it makes an abrupt bend of 90 degrees, this gives the antenna a small directional gain which causes an increase in the E. R. P. over a 200+degree pattern. This antenna's design also delivers a F/B ratio of approximately 6 to 7db. The antenna demonstrates excellent performance out to approximately 2000 miles and continues to perform satisfactorily at more than 5000 miles making it very desirable for a wide range of communication applications. So regardless of rather you are a local net controller, a east or west coast Rag Chewer for a serious DX hound this one antenna is ready for the job at hand.
