I've installed a number of antennas on aluminum body Fords.Thanks all for responding. Looks like I'm going to drill. Larson makes a mount in 3rd brake light but costs more than the antenna and installation. Stay safe
I used to use one for 220MHz ham communication; didn't like it too much since 1.) it was only a 1/2 wave, and 2.) I couldn't get the SWR as low as with other antennas.Is anyone using glass mounted antenna in the central part of the state. Just wondering, don't want to drill hole in my aluminum truck.
