Hi, can anyone in here verify that there is an antenna on ALL of the trucks, or do only the long range units come with antennas?

Also, if there are antennas on all trucks, where is it located? I've called two dealerships and no one can tell me IF there's antenna, and where it would be located.

Thank you!!!

FOUND IT!!!

On the crew cab, it's located in the C-pillar on the drivers side. If a passenger is sitting in the rear, on the drivers side, the module is just behind the plastic trim that covers the seatbelt and other stuff. The antenna actually stems off of that module, and runs just under the plastic trim to the bottom of the back window. I extracted the antenna for some testing and have improved my range by taping the antenna straight up and down on the back window (just where the seam of the window and body meet). I'll be doing some more testing, but I tested before and after, and so far it has doubled the range. Thank you Jackie for sending the schematic!!!
