How much difference does a metal pole make when it's sitting in the middle of all the lower elements of my beautiful new highly optimized to the max YO.EXE 10 m yagi ?
I get it that the closeness of the pole will mess up the impedance a bit.
But the elements are still there in the right place with the right length constructively adding to and destructively subtracting from the incoming signals (for example) and after a few tests it seems that a metal pole makes less difference that you might think.
Does it just affect the radiation pattern in the elevation plane ? Can anyone tell me if actually a metal pole which only goes up to the boom lowers the angle of radiation .. imagine that ! a rare case of owning aan antenna cake and eating it at the same time :o
