Or you running those two wires as a “balanced low Z” audio line? Or one carries audio and the other carries the voltage from the power supply for the transmitter?
Balanced line is 2 wires carrying the audio inside a shield. Unbalanced is one line carrying the audio inside a shield.
If only one of the wires is carrying signal inside the shield, then losses over 100 ft can be considerable.
Secondly, is it at all possible that water could have gotten into the audio connection or cable at the outdoor end? That can really sap your signal with either balanced or unbalanced line.
