Not just a suggestion, but a STRONG recommendation. But leave the word 
"balun" out of this sentence.  It is a COMMON MODE CHOKE -- a section of 
parallel wire line wound around a lossy ferrite core that forms a very 
low Q resonant circuit. The parallel resistance at resonance is what 
chokes off common mode current.

The word "balun" is highly confusing, because it is used to describe at 
least a half dozen very different circuit elements -- everything from 
tuned lengths of transmission line to actual transformers, to arrays of 
common mode chokes, to electronic circuitry to modulate baseband video 
onto CAT5 cable.  .
