What's the percentage current unbalance on the balanced line when there's a

You didn't give enough information for anyone to provide a valid answer,
Reg. What is the impedance from the junction looking back toward system
ground? If it is three ohms, a balun is necessary. If it is 300 ohms,
you can probably get by without a balun.
