There is a smaller hole in the center where the opaque retainer sticks through as shown in the first picture. The bottom one shows two examples with the retainer/antenna removed but the seal remained. Most of the time it comes out when you yank the cable and retainer but not always on a Mustang/Shelby
Great info!
