No process.  I am blindly trusting what the antenna section 
of the handbook tells me.  The only thing I am wondering is 
if XL=XC as the height of the dipole changes.  Height 
evidently has a dramatic effect on the feed point impedance 
value according to the chart.  It was just not clear how 
height effected the resonance condition if it was effected 
at all.
