Antenna Nub Things?

I'm wondering, do they make anything like a little screw-on nub type thing, for antennas?

Such as I never use the radio, so I thought it might be cool to unscrew the antenna and screw on a little "cap" type thing, that's maybe either black or body-colored.. that would be cool.

anything like that exist?

i think i might just make something since no one makes anything like this because i want something like this also

I deleted the radio in my car. Unscrewed the antenna, and put a small black rubber vacuum cap over the projecting threads. You can sort of see it in this pic.

I ordered a power antenna for mine. Just going to hook it up to a manual switch so I can put it up and down when I want to. :cool:
