Well now I am not sure what you want plotting if you are making the
reflector resonant
other than the design frequency of the array.

Art:

No, the reflector would remain the same ~5% longer (electrically and
physically) than the de. And, the director remains physically shorter
than the de, but made resonate with the proper addition of a coil,
somewhere in its length, so as to be made resonate at the same freqs as
the de (or approx. so, since the coil will undoubtedly change some
characteristics from that of the resonate de.

Art, you are rapid losing me here. Either I am not able to see what you
are getting at, or else I suspect you of having some facts or formulas
twisted about here...
