Displaced Element Dipole and feed question
John S wrote:
Suppose I have a dipole where the two quarter-wave elements are not exactly aligned. That is, the axis of, say, the left element is displaced by some amount from the axis of the right element. Then, what about feeding them from a balanced line? The questions a * How will the antenna impedance and current distribution suffer, if at all? * What feed system is required? 90 degrees to the axis is preferable, but that means that the twin lead has one side longer than the other. Is this interesting? Or, has it been discussed before? What was the outcome, if any? Thanks, Guys. What happens highly depends on what the offset is in wavelengths. If it is small engough, nothing happens you could likely measure. As for feeding it, you connect the ends with another wire and feed it in the middle of the connecting wire. -- Jim Pennino |
