The resistance depends on the distance between the elements and on the ratio between the length and diameter of the material used. The 3D radiation pattern of an ideal dipole antenna is a horn toroid (a doughnut without a hole). The gain as a function of the separation is shown in Figure 2. I also have other nec files for the different gsm bands, gsm-550_6element_yagi. YAGI is a software application whose main purpose is to help you learn more. Design data for your yagi.
