What are the four antennas on the back of mygig?

[SummitJeep]

Does anyone know what the four antennas are that come off of the back of the mygig and where the antennas themselves are found? I know the am/fm is obvious, and then there is the two under the top panel on the dash, but the last one is missing in location and what it does.

Thanks

Does this help?
