CUTLASS Probably the dumbest question....(antenna removal)

I got my new car cover today, just to keep the Cutlass covered in the garage and keep dust and such off. I want to remove my antenna so I can cover the car, mark the antenna spot and then punch through the cover and use my plastic grommet to make my antenna hole. Either I am an idiot or I am over thinking this or both. Shouldn't the antenna just be mounted (screwed on to a post) to the base? I can not get it loose and don't want to damage paint or the antenna. Am I missing something?

Points all taken. I will just leave it on and take some good measurements for the hole. Glad I wasn't over thinking the the issue and not crazy at how tight it is lol.

Here is what I did. I took measurements from my previous cover to get me close and marked the new cover. I then put the new cover on the car checking the mark I made on the new cover for the hole for the antenna. It was pretty close. I re-marked the correct placement and then used a sharp fresh razor blade to cut an X for the hole. I then confirmed hole was almost perfect to where it needed to be. I then take the old cover and the I cut out the plastic grommet from the bottom of the cover where a bungee or cord would go to hold the cover on. I cut approximately an inch of material all the way around it. Then I use a small dab of CA glue to hold it. Then I use ShoeGoo to attached that grommet by its material around it. After it dries, I do another coat all around the top and let it cure for 24 hours. Now the hole for the antenna is relatively tear proof! The car is 100% garage kept so the cover sees zero wind. So this works very well. Did it on my last cover too. Removing the antenna just makes marking the hole for the antenna. This is how it turns out. This is a Budge Car Cover, size 4. It will stretch a good bit after it is on for a bit and fits even better. 😁
