I just got the Delphi Skyfi set up for my 2000 Explorer XLT. Installation, using the stuff from Crutchfield looks fairly straightforward. I'm wondering where to mount the antenna. I see from some posts that a few of you have mounted them in the rear and run the cable through the tailgate. I'm worried about interference from the roof rack and was thinking more of placing the antenna near the front or at least mid-roof. I'd appreciate any thoughts on this and any advice on running the cable, etc. Thanks for all your help!
