What are all these antennas for? What about gain on the curly one?

The one on the left is a standard 5/8 over 1/4 wave collinear for 800 MHz. They have around 3 dB gain over a dipole. The others are low profile antennas. I can't tell by the photo what bands they are for.

On cars I've seen, Usually body mic receivers, DVR upload, and cell modem. Usually a gps somewhere too.
