Under the battery cover are the 2 torx screws, just next to the battery door latch. Removed those 2 screw, fully extend the antenna and the grey part will come off with the antenna. There are 2 snap tabs that help hold the grey section on on the upper section, but usually comes off easy. There is a small phillips screw that holds the black section of the antenna in place.
Hope this helps ....
