Surprisingly, I think I see the difference now between the Tarnado and the V58, and you're right Camaro1. The V58 bottom end of the coil is connected to the ground radial bracket, and this antenna does not. Camaro1, you did not tell me if the bottom tube for the radiator came in the kit already installed into the base assembly. If this is the way it came, already installed in the base, can you give me all of the dimensions for the bottom part up to the point where the adjustment for the length of the radiator is made? If you can do the measurements for me give me the length and diameter of the rod between the coil and the center conductor for the feed point.
