    I would like to submit the following as my contest entry. For now I have created a pdf file with notes and some instruction on what I did to make the Cactus Super J-Pole. As soon as I get it all completed and operating I will add more pictures. Below is two pictures of the main antenna ready for Clear Lacquer Finish and then Final Assembly.



    The Antenna is a Cactus Super J-Pole for use on 2 Meter and 70cm. I will post how it works once I get it operational in the next few days.

    The PDF can be downloaded here

    It looks great. Get it in the air and let us know how it works out.

    The Super J-pole or extended J-pole or whatever the name is works fairly well. I built one several years ago using 3/4 inch copper for the bottom and 1/2 inch for the top 1/2 wave section. I was surprised it tuned so well. I could see a slight difference over a vertical 1/2 wave dipole so it does have some gain. Your project looks good but it will look better up in the air. (y)

    Looks good! I renamed the thread to help people find information about this antenna.
