re: ZS1AN's cascade
Are we talking ferrite loaded TLTs (transmission line transformer) or flux coupled transformers and ferrite loaded "chokes" in his design?
I can never keep this current-voltage balun stuff straight.

I've been intrigued by the ZS1AN's cascade of a voltage "Balun" for the 
impedance desired, followed by a current Balun to ensure balance.
