i was behind a slk 32 the other day and noticed they had a very short antenna - like a stubby. does anyone know if this antenna would fit our cars? and if so, would it help or hurt reception? if it fits and doesn't retard reception, i want one.

[it was from my phone so it's a small pic but if you look real close, you can see it. comes up and stops 1/2 thru the side mirror]
