Perhaps CC should add one tower  to WHYN,


The problem both WHYN and KLVI face in trying to make them play digital is  
the high RSS/RMS design, coupled with the very low base impedances of the short 
 towers. That's a lethal combination guaranteed to produce poor impedance  
bandwidth and poor pattern bandwidth. Both arrays suffer from inadequate space  
phasing. Pushing 145 to 155 degrees of phase difference between adjacent 
towers  only 90 degrees apart is the culprit. The best way to fix these would  be 
to substitute a broadside pattern configuration or parallelogram instead  of 
the endfire. Another tower or 2 and more land for sure.
