BALBALs advertised lately.

one thing i neglected to mention is that the rig is grounded;
according to the roy lewallen document i referred to, the ground
connection causes imbalance, regardless of the ladder line;

When I ran into the same problem, I decided to adjust my
ladder-line length per band so the balun would always be
looking into an impedance between 35 ohms and 85 ohms.
