Yes! I have tried it and it works well enough. When using 
well constructed transformers, there is very little common 
mode noise transmission. Impedance is 100 ohms. Loss is 
about 1.2 dB per 100 feet at 3 MHz. Keep it away from 
metal objects. Ground the center-tap of the transformer to 
prevent static build-up. Be aware of cheap cables that may 
have higher losses.
