Getting any phased array properly aligned and optimized is never a case of
throwing it together with fingers crossed. Sure, it may radiate, but which way
and how well? Adjustable LC networks make it possible to compensate for the
actual feedpoint impedances. But it is a process. I learned how to do it by
studying ON4UN's Low-Band DXing. Here is a link to my report on a 2-element
phased array that used those techniques:
