   Well, not that the core is out and free, I will use today to create 4:1   
   Balun. I am thinking to build 2 core Guanella version (not stacked), which in   
   essence is a design based on two interconnected 1:1 Baluns. I've read on the   
   net that this design is the "real" 4:1 Balun, compared to the single core   
   design which does not provide stable balance to unbalance transformation, and   
   that it is possible to provide the common current to the shield of the   
   coaxial feed line.   
   I will appreciate if someone have comparison experience based on usage on   
   these 2 different designs..
