I did not "relocate" my stock antenna, but I did use the Antenna that came with my Sirius radio and put it in the center of the hood just behind the washer sprayer.
I had to change the antenna location because I installed a foil lined insulated headliner I made, which blocked the stock antenna's reception.
I get great reception now.
