I should have re-stated my post last night - several of you have 
responded like Steve did in stating that YO does not recognized lumped 
loads.

I guess what I am asking for is a model with the equivalent full sized 
elements... I am designing a 3 element version of the Cushcraft 
employing some Telrex pieces and parts in my stockpile... it will be 
through the boom elements and am initially aiming for the olde fashioned 
.20/.15 3 element yagi spacing we used before we had modeling programs. 
 So it is a "full sized" boom but with the shortened elements...

SO -  if you have a YO model of the 40-2CD which uses full sized 
electrically equivalent versions of their lumped inductance element 
please forward me a copy.

Thanks,

Jim, K4OJ
