I recently bought a used car and it did not come with an antenna. There is a cap where one should be and a wire runs up to it.

personlly I would like a short one (6" or less).

What antenna would you recomend?

I'd recommend the biggest one you can fit. Generally speaking, more metal in the air makes for better receiving. Having an antenna tuned for the frequency you're listening to is of a slight advantage, often more than offset by having a bigger antenna. 2 and a half feet would probably be about optimal for auto usage. That's 1/4 wavelength in (roughly) the middle of the FM band. A 6" antenna is going to be less than 1/16 wavelength and not tuned at all. Might suit your purposes if you only like strong/nearby stations, but definitely won't be ideal.
