In dual GTX transponder installations, each transponder must be grounded separately using
separate ground terminal/stud locations on the aircraft.
If practical, power and ground wiring should be routed separately for each transponder.
Route grounds and wire separately to improve safety if there is a wiring or grounding system
failure.
