 I'm going to show ignorance here.  I would think that a capacity hat would be something like a disc or a Yagi at the top of a vertical pole.  A 132 ft sloper would be an antenna with some impedance at the loaded end resulting from the geometry of the antenna.   I would think that EZNEC should give you some idea of that impedance.  How were the results weird?  Thanks,  N0UU
