[Ham-Mac] Yagi generator?

[EZ Rhino]

Hi guys-

Is anyone using any yagi dimension generator programs and/or programs  
that can generate gamma match dimensions for user defined antennas?   
(For Mac?) I have played around with RF Toolbox a little; I have also  
found a couple PC programs using google, but nothing real  
sophisticated for Mac.

BTW, I'm using W7AY's CocoaNEC for modeling and it is fantastic.  He  
did a good job on that one.
