We have seen great performance from the Procom *MU 4-MM/CEL4*, which is a magnetic mount car antenna for the 410...430 MHz range:

The same antenna type is available for other sub-bands commonly used for tetra, e.g. 380-400 MHz (CEL5)

Antennas can be ordered from a variety of distributors such as e.g. "ukw-berichte":http://www.ukw-berichte.de/ (Part #P130000912)

Please note that the antenna ships without any cable.  The magnetic mount has a FME socket, so you will likely want to

order some FME-to-FME cable (ukw-berichte part #20227) as well as a FME-to-SMA adapter (ukw-berichte part #00218)

There is a nice combination available from "DG0VE":http://www.dg0ve.de/: A ~ 20dB LNA with a double-helix filter (10MHz band-width).  It's called *LNA 70-1* and can be custom-ordered with e.g. a center frequency of 425 MHz: http://www.dg0ve.de/LNA70_1_2010_001.pdf
