Howdy all...I am looking at constructing 2 W2DU bead baluns as described in ARRL Antenna book that uses 12 Amidon FB-77-1024 beads.

Not trying to change your mind, but you get more balun for the money with multi-turn
toroids. Multi-turn toroids yield a choking impedance proportional to the square of the
number of turns. Turns are cheap. W2DU baluns yield a choking impedance proportional
to the number of beads. Beads are expensive. I have the very W2DU chokes that you
want to build and don't use them.
