Antenna replacement

I am looking to replace the stock Antenna on my 03 cav. I want something short and stubby but don't know what will fit. after looking at ebay i came to the conclusion that i need a female antenna, and after measuring the stock one with a ruler, i think a 5mm. Would it tell the right fit in my owners manual (which is at home and i am at work now)?

Just about any antenna you can pick up from a checkers or pepboys will work fine. Most ants are universal. Right now Im running a $8 shorty ant I got from pepboys and it fits great as well as gets better reception then my stock ant.
