I thought it was showing the performance of both antennas with the same
power level, 100KW. 

So, I looked at the graph again... 100KW *ERP* as opposed to TPO.
That little fact escaped my attention the 1'st time.

Remember, I'm an AM guy. I'm still learning this newfangled FM stuff! ;)
'tis a whole 'nuther world, indeed.
