Dave Wise gave a good answer, but left the deaf balanced input.

If the plug and jack numbers match up, then the Balanced input
really is balanced. This means that it rejects common mode signals.
A single wire antenna, being unbalanced, produces a common mode
signal that is rejected. That, or the plug is shorted.

Try a dipole antenna with one lead to each balanced input pin.
Or, ground one pin and connect the long wire to the other.
