why you couldn't just add a husky 1:1 W2DU style choke
on the 50 ohm side of your 4:1 voltage balun to inhibit
common mode current. The extra toroid in the afore mentioned
QEX article is a 1:1 choke attached to a 4:1 voltage balun.

Did you read the article Cecil? He place the current balun/choke on
the opposite side. Looked like an interesting approach.
