Mine is a 2-dr and the factory sat-ant is located above my left ear while sitting in the drivers seat. It's under the padding on the rollbar above. I also have bad issues with reception due to the rack and have yet to get the aftermarket plug in antenna that I'm going to relocate somewhere. Right now I'm considering the drivers side vent surface close to the windshield wiper, the antenna is the size of a quarter, black, tiny wire and plugs into the factory location. This way I can leave my stock setup alone and reuse it down the road if I ditch the rack.
