Any balun that has a DC path between the center conductor and shield will
take care of the static buildup problem. Balun designs vary, but all the 4:1
current baluns I have do have that DC path. If you aren't sure what's inside
a balun, you can make a quick check with an ohmmeter. A reading of near zero
ohms between the center conductor and the shell tells you that the DC path
is there.
