The location in the picture is single pane glass. It's what works on the glass mount cb antennas. So many people complain about the glass mounts because they mount it to too thick laminate glass.
Spend 20 bucks on a glass mount, put it right there in the picture.
This where and how mine will mount. It's number 241 on a mod list of 512 so it'll probably be a while, but the research is done and the book is closed for me.
(and your mount idea wouldn't have worked anyway due to a regular antenna needing to be mounted to metal for a ground plane that's counter to the antenna.
Glass mounts and specialty antennas do not need metal to mount to.)
