[Towertalk] split end on coax for Yagi connection?

[n6tqs@arrl.net (Doug Faunt +1-510-655-8604)]

Hi people, 
Another basic question: I need to split the end of the coax
to make pigtails for the Yagi connection for the local club Field Day
beams.  This is the second set of coax cables I've run across where
the pigtails went bad, so what's the way to do them properly?

I'm using ferrite choke baluns for my own stuff, but can't convince
the powers that be that they'll work just as well as coils of coax,
and are a lot cleaner.
