I also thank you for starting this thread, it’s the first time I’ve looked for the animated eating popcorn thingy. These folks went off!
To answer your question I’ve been using fender mounts for various trucks and an NMO antenna. If you don’t know it’s the commercial style antenna. I think they are cleaner and maybe work better than a short fiberglass antenna. Mounting is all a trade off. Radio signals need a ground plane for efficient and effective radiation. Middle of the roof is best, but me as a nerd don’t want to do that to my truck. So the next best thing for me is a fender mount.
The more metal around the antenna the better it will work. Example of its the middle of the roof it will broadcast the best in all directions.
A third brake light mount will favor to the front.
A left fender mount will favor to the right.
I have both HAM vhf and uhf plus CB and GMRS
There’s uses for it all, I’ve remote mounted it all behind the right rear seat on a Built Right bracket. That was in my 2018 F150.
Waiting for my wife to look the other way before I buy stuff for the new truck
Sorry if you k ow all this already.
If you have questions DM me and we can bypass these clowns.
