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.
