The manufacturer says you MUST use a 2:1 balun rated for 5 kw. Just asked 
because those numbers at feedpoint sounded strange for me. It´s a very 
popular antenna anyway. 73s and thanks for the reply. 73s!

What does the manufacturer recommend?  Would the 2:1 balun be for 100 ohms
rather than 25?

I would try to get feed point impedance to 50 ohms then use a standard 1:1
current balun or RF choke.  A hairpin coil usually is a good device to set
impedance for a Yagi.
