Whip Antenna Length

I'm actually embarrassed that I have to ask this, but it's been that long since I've cut a whip antenna, and I've forgotten.



When I'm cutting a 5/8th wave mobile whip, do I also have to account for the length of the space between the contact pin, and the bottom of the insert space for the whip?



Thanks guys. CRS syndrome setting in...
