[CQ-Contest] Magic GP antenna

[Zack Widup]

Hi Zoli,

Did you try modeling it also with MININEC or NEC2? I have never used the
MMANA program but I have used Yagi Optimizer. I always check my designs with
one of the above two programs. Usually they agree closely but sometimes they
don't, in which case I throw out that design.

It would be interesting to see what one of them predicts for it.
