Herb-
Now that I know what your game plan is, I will try to model it for you and see  
how EZNec says it will perform. My copy is only NEC 2 and I have heard NEC4 
does a better job but I don't have a couple kilo-bucks to shell out so it will 
have to do. I have AC6LA's optimizer which will make it easier.

NEC4.2 is $300 for a non-commercial individual license.

Most tools that use the NEC2 back end can use the NEC4 back end with no changes- the input and output file formats are essentially the same.



BTW I don't see any reason why your old F12 element brackets can't be relocated 
on the boom should it prove necessary. If your beam is built the way several 
that I have had were, all you would need to do is drill out the rivets and move 
them.
I will try to get this done before the weekend is out. Please if someone else 
has already done it, let me know today if you can
