For clarification regarding the antenna on this new Voyager system, the camera has an antenna directly on it and the monitor has an antenna directly on it. There is no wiring other than the wiring at the rear cap that ties into the running lights for the power feed and the wiring for the monitor to the cigarette lighter where the monitor receives it's power. The running lights must be on for the system to work. Here is a link to the new system:
